Head Tale

Facebook has stolen added a new feature, inspired by Twitter, where you can tag another user by using the “@” sign and then typing the person's name in your status updates. 

When I was trying it out to tag Shea in a post, I ended with a rhetorical “Is this a Twitter killer?”  A few people were quick to respond that this wasn't the case with one very succinctly saying “Um…no.”  

So I should clarify what I meant with my half-baked comment.  I obviously don't think that one appropriated feature, no matter how core to the experience, means that Twitter's going to disappear (although they appear capable of doing this to themselves regularly anyhow!) 

But I do wonder if the rapid Twitter-ification of Facebook does mean that the casual user (here I'm talking about people who aren't early adopters, who don't work in libraries and get excited about every new technology that comes along, and yes, I'll say it, the type of person who answer a LOT of Facebook quizzes) might be less inclined to make the jump to getting on Twitter if they're already on Facebook?

Nah, those people can still follow Ashton Kutcher and Britney Spears if they join Twitter. They'll leap too!  
(Now, as for whether MS-Office Online will kill Google Docs, that's a much more plausible scenario…)
