It seems as if Twitter hit one of those famous big steps in traffic, the increase has halted to a mere 1% up, says Compete, who also thinks that this means that Twitter clocks in at 19.7 million visitors. That’s a whole lotta twittering going on. I wonder when we’ll get some stats on how many users are actually using Twitter, since these things only track the web visitors, and I rarely load up twitter.com myself, preferring Tweetie and similar stand alone applications.
