While the retweet button is similar to like (my co-founder and I actually discussed this the day before), I do think that a Twitter Like button may come along eventually. In fact, I think it's even possible for an upstart Twitter client to decide (on its own or with some of the other clients) to implement a Like button protocol, in the hopes that Twitter would eventually adopt it. Like buttons are great for monetization, so I think it could make sense for Twitter.
