Not-yet-documented Twitter features: colors for hashtags and replies, red highlighting for text over 140 characters
New to Twitter, not yet mentioned on Twitter's blog: That service's Web interface now displays hashtags and @ replies in whatever color you've set it to display links in (the default is blue, but you can change that in your settings' Design category) and highlights any text over its 140-character limit in red.
Not a big deal, but it does show a welcome willingness to keep improving a Web app that one might consider "done." If only Twitter would show the same attention to all of its smartphone clients before trying to kick out third-party apps.
