So, Facebook opens up access to a number of Facebook Applications including status updates, notes, links and video, and suddenly, people like Nick O’Neill at AllFacebook think we’ve got a Twitter-killer on our hands.

Mark Hendrickson at TechCrunch gives this theory a well-argued smackdown:

“Facebook fails to challenge Twitter with this new platform upgrade because the two companies ultimately serve substantially different behavioral paradigms. [...] Something behavioral about Facebook’s users would have to change, and it’s unlikely that these users — who are largely mainstream — are inclined to pick up the tweeting habits of a crowd that consists mostly of early adopters.”

MG Siegler at VentureBeat examines the dynamics of the relationship between Facebook, Twitter and Friendfeed, and reckons there is definitely room for harmonious co-existence, given how differently users approach these different tools.

“…rather than Facebook killing Twitter, Twitter may thrive with the more open Facebook. A lot of people use services that automatically pipe in their Twitter updates to their Facebook status (which again, leads to a lot of messages that make no sense), but now you should be able to do it the other way round, too. And that will actually get me using Facebook status updates more, because I will use it if I’m going to say what I’m actually doing and let it get sent back to Twitter. But I’ll continue to use Twitter for the other micro things I want to say.

Now on to FriendFeed. When people were busy saying that FriendFeed was going to kill Twitter, they forgot that the two in some ways have a symbiotic relationship. A lot of FriendFeed’s user data comes from Twitter (I don’t know the exact numbers, but my friends’ top sites area on FriendFeed’s stats page shows that nearly 75 percent of the content from the people I follow comes from Twitter — that’s huge). And now, with the ability to send messages back to Twitter, I’m sure FriendFeed is sending its fair share of updates back the other way.

The two feed off each other, and the same thing might start happening with the Twitter/Facebook relationship, now that the data can flow both ways.”
