Even as we applaud the use of crowdsourcing to find terrorists such as those who bombed the Boston Marathon, we must caution over the sharing of uncorroborated accusations and “news” via social media. CNN famously got a lot wrong both during and following the initial Boston Marathon bombing crisis, including sending out updates that erroneously stated that the police already had a suspect in custody. And if a major news outlet is fallible and can mislead the public, just imagine how badly untrained but eager-to-help social media users can can screw up. And screw up they did, when spreading the picture of Moroccan teenager Salah Barhoun around as a suspect in the Boston Marathon bombing.

4Channers and Reddit users are among those on social media sites who are part of a new wave of citizen cybersleuths – or “crowdsleuthers” as some are calling them. The concept of crowdsourced terror investigation isn’t new, but it’s in the news like never before since the Boston Marathon bombing.

If you can’t access LinkedIn (does anybody really use them any more?), it’s not just you. Yes, LinkedIn is down.

Twitter is trending with the promoted hashtag #AmexSync. Do you get annoyed with the “deals” that your Facebook friends “like” showing up in your newsfeed? Well prepare for it to get even worse on Twitter, as American Express and Twitter introduce Amex Sync, the service that connects your American Express credit card directly to your Twitter account. And rest assured, as Twitter has proven time and time again, your private information is secure behind their hack-proof system. (Not!)

Congratulations! If you received a LinkedIn email telling you that your profile is one of the top, most viewed profiles on their site, you should feel special.

Just like the other TEN MILLION unique and special recipients. Better known as your fellow top, most viewed profile recipients.

The latest e-marketing campaign by the business networking site is somewhat of a double-edged sword. On one hand making recipients feel special and unique like a snowflake—till the simple math reveals that being one of their top profiles makes them not even one in a million.

Tired of having to resort to eBay or Craigslist to sell the stuff you no longer want? Or trying to give it away on FreeCycle only to have some overzealous moderator reject it? So was the creator of GTSList.com, the online garage sale where you can sell your stuff to friends and family, for free, and while keeping it private so you are not opening your home to random strangers. GTS List takes the idea of the online yard sale that often takes place on sites such as Craigslist, and combines it with the experience of having an old-fashioned yard sale, by making it a virtual yard sale. While a virtual garage sale is nothing new, we think they’re on to something by giving sellers the ability to keep their sale as private as they’d like.

Facebook has proven to be a time again, but this time Facebook has risen to the occasion. Well, its users have. Facebook users banded together and have saved a gay dog from certain death, at least, a dog that was surrendered to animal control by his owners, on the basis that he is gay.

If you’re tired of the privacy concerns of Facebook, the anonymous social network called Social Number may be right up your alley. Giving the question, “what’s your number” a whole new meaning, Social Number lets users pick a user number, which is their only identifier on the social network. That means users will not have user names or identifying photos, just assigned numbers.

YouTube (or “Utube” for those who are too lazy to type “Yo”) is preparing to launch channels with paid subscriptions to its video lineup. Channel owners can apply to have a premium channel, and YouTube is hoping that channels with specially designed content will draw more users. It looks as though premium channel subscriptions will cost somewhere between $1 and $5, with the first channels launching as early as the second quarter of this year.

Twitter released their new video sharing service, Twitter Vine, Thursday, which allows Twitter users to film and share small, six-second-long looping video clips. Twitter says that these small little snippets are in line with its model of Tweets being limited to 140-character-or-less model for Tweets. Michael Sippey, Twitter’s vice president for product, wrote about Twitter Vine on Twitter’s blog on Thursday, “Like Tweets, the brevity of videos on Vine (6 seconds or less) inspires creativity. Now that you can easily capture motion and sound, we look forward to seeing what you create.”

The French-language version of Twitter has been an ugly and contentious place lately, and the French government is taking action. With recent hashtags of #SiMonFilsEstGay (if my son is gay), #UnBonJuif (a good Jew), and #SiMaFilleRamèneUnNoir (if my daughter brings home a black guy), the Grand Instance Court in Paris has ordered Twitter to create a way to alert French authorities of illegal content when an offending tweet is sent out.

We all know that half the battle of getting a job interview is a killer cover letter. One student majoring in finance who is looking for an internship on Wall Street in New York has written a cover letter that has become a viral Internet sensation because of how blunt and honest it is.

The social media world is buzzing with opinions about the new Myspace now that they have released the new version. Ever since it was announced that Justin Timberlake was one of the new partners involved in reviving the dead social media site, the Internet has been flooded with speculations as to how the newly revamped site will compare with Facebook, Pinterest, Pandora, Songza and, of course, how it compares with the old Myspace.

Twitter users will soon start seeing #TwitterArchive trending. Twitter has announced that they are now allowing users to download their entire archive history to store for their own personal files. The archiving feature will allow users to download past tweets and retweets, and users can look at their archives by month and search keywords, hashtags, usernames and phrases.

American Association of Retired People (AARP) has partnered with HowAboutWe.com to offer online dating, for older, senior singles. While Internet dating may seem to undermine the old fashioned (i.e. face-to-face) way of dating that single folks of the retired generation may appreciate, HowAboutWe.com has created a way to mix old fashioned dating with online dating, in a way that users from any generation can appreciate.
