Looks like Twitter is launching its own Tweet buttons later this week. While you can already embed the code (see below), not everybody can actually use the button to retweet the post yet.

Just for the sake if it, I have embedded the code (courtesy of Mashable) here.

I’m guessing we will see a new wave of discussions about Twitter’s relationship with third-party developers over the next week, as this move will likely put Tweetmeme (which is more well-known for its retweet buttons than for its core product) out of business in the long run. I know I wouldn’t invest in a Twitter-releated company at this point…
