Today on the Twitter blog, the company wrote a post that was all of three sentences to let people know about their new logos. Yay!But there’s actually quite a bit more to it then it seems.If you follow the link they provide to Guidelines page, you’ll find some interesting tidbits. Among them:Don’t: “Use anything other than the most current versions of the Twitter logos.”Don’t: “Use screenshots of other people’s profiles or Tweets without their permission.”Both are interesting because both are broken all the time. Well, okay the first one doesn’t quite count yet because Twitter just officially launched their new logos. But hundreds if not thousands of sites around the web have been using old or fake Twitter logos to represent the company for a long time.The latter rule is definitely more troublesome. Tweets are known to be public items, but Twitter is saying you can’t use screenshots of them without permission. We do this all the time. So does just about every other publication. We’ve never been told this is wrong, it seems to reek of fair use, but now Twitter is saying it’s a no-no.A few months ago, Twitter tried to come up with their own solution for this with their own Blackbird Pie tweet embed tool. It’s interesting that in their post on it, they never said this screen-grabbing of tweets was wrong. In fact, they note “Mostly, we just think it’s a pain to take screen grabs of tweets.” Notice they call it a “pain”, not “wrong”.Twitter does say it’s fine to use others’ tweets that you have permission to use. But again, isn’t this stuff already public?Also interesting:Do: Make sure that if mentioning “Tweet,” you include a direct reference to Twitter (for instance, “Tweet with Twitter”) or display the Twitter marks with the mention of “Tweet.”This would seem to be all about Twitter gaining the trademark to the word “tweet”, which they’ve been trying unsuccessfully to do. They also later note, “Please remember to capitalize the T in Twitter and Tweet!” As a commenter notes, it’s funny that they don’t even capitalize it in their own logo!
