It's "just a feature" (I don't agree with this, btw - it's a service) with about a billion separate implementations (brightkite, facebook status, jaiku, friendfeed, tumblr, etc, etc), and yet it still exists as the market leader in the space even though pretty much all of these sites do it "better" in some way.

Did you write this article simply as linkbait, or do you really believe it?

Simply showing up and saying you can migrate data from one into the foundations of another doesn't at all sustain any sort of argument that a distributed Facebook Status model will "kill" Twitter. The modus operandi is drastically different between the two sites. Twitter isn't a "feature", it's a "service", a highly extensible and mobile service. The fact that it is focused on such a simple protocol as telling people what you are doing, imo will ensure its longevity.

Given that people look at Facebook statuses as a mere extension of a user's profile, versus a Twitter timeline actually serving as your profile, simply distributing your Facebook status on a web page isn't going to phase Twitter one bit.

And I still stand by what I said earier: Facebook and Twitter users aren't the same. Mark might update his status on Facebook "Mark is at the ball game" but on Twitter, he'll probably say "Local sports team is up by 4! Go team!". The inherent purpose and utilitarian value of the two sites are completely different for one to arbitrarily overthrow the other, just because the one (Facebook) mimics the distribution of the other (Twitter)

Statuses on Twitter and Facebook are just text fields, although Facebook's starts with your name. The differences between how they are predominantly used are results of socialization, and many people use Facebook statuses like you've described Twitter's and vice versa.

My Twitter network is completely different from my Facebook network.

That is why Facebook can't easily kill Twitter.

Add Facebook Connect and a way for people to import all their twitter updates in 1 minute and you've come up with an easy way to kill Twitter

Twitter is a really easy service to underestimate. If Facebook could wipe out a competitor that easily don't you think they would have done this already?

Okay, I will prove my point using what you've just said: if people are importing their Twitter feeds into Facebook, instead of letting Facebook status serve as their alert beacon for friends, what do you think that says about the user value of Facebook status updates?

For some people at least, Twitter beats Facebook simply by only doing statuses and not exposing you to all the other crap.

With Twitter, I don't have to waste my time ignoring the latest Knighthood Invitation or the Group Created to Get Enough People in the Group to Advance Cause X w/ No Substantive Effort Invitation.

It would take more than a day or two. There are good points that can be made as to how FB could take on Twitter. FB has enough cash to do the job well if it wanted to. FB could also decide to become open in certain aspects and stay closed with other features. Anything could happen. I only want to see Twitter stick around to see more competition. Otherwise I could care less.
