Twitter's had a major lick of paint - and, for once, it's across the spectrum with the web and mobile apps redesigned to give them a fairly unified look on both the iPhone and Android (iPad owners are still out in the cold, though we don't expect that to last.)
Users now have four main tabs which consist of Home, Discover, Me and Connect. One cool new ability is that to just see those who have mentioned or retweeted you - handy for those of us who are extremely popular (he says, wishfully!).
You're also now served up topics and hashtags tailored specifically to you interests or wherever in the world you may be.
It's certainly nice to see some cohesion between the Android and iPhone apps which have long come in different flavours. We're not sure yet when Windows Phone users will get theirs.
But as is always the case, change does not please all. Indeed, looking at the most recent comments in the Android market appears to show a loss of support for Twitter's official app with many rueing the loss of the clean, simple look Android users smugly preferred over their Apple counterparts.
And of course, this will only affect you if you use the official Twitter app. Such is the nature of the service, that many others can legitimitely tapp into Twitter and the likes of Hootsuite, Twicca, Seeismic and UberSocial have no plans to change that we know of. If you use these, you probably won't even notice a difference.
