Silver members on XBL, good news! Kinda. Facebook and Twitter will be accessible to you all. The 'kinda' part in this news: it's only for a limited time only.
Microsoft told VG247:

Facebook and Twitter on Xbox LIVE will be free to Gold members, with a free trial period also available for Silver members (emphasis ours). Facebook and Twitter on Xbox LIVE will offer a truly one-of-a-kind social experience, completely optimized for the TV and seamlessly integrated onto your console. Add to that exclusive access to Last.fm, Netflix instant streaming, demos, trailers and discounts, plus the best multiplayer gaming network on the planet, and we re confident Xbox LIVE Gold memberships is hands-down the best value in home entertainment. We re committed to adding new features and value for our Gold members, and will continue to do so.

There you go.

Twitter has reportedly ramped up its legal team by hiring away a key Google lawyer to become its general counsel. The site has nabbed Alexander Macgillivray, the former Senior Product and Intellectual Property Counsel at Google, reports the NYTimes.

Macgillivray’s resume is extensive: he steered the Google Books settlement with publishers, which if approved by a federal judge could pave the way for Google to scan and index millions of books. He also handled Google’s conflict with the Associated Press and defended YouTube against Viacom’s lawsuit.
Few Legal Issues

And yet Twitter’s legal issues have not been extensive: with the exception of recently-dropped La Russa case, in which the baseball manager was angered by someone impersonating him on the site, Twitter hasn’t found itself in legal trouble. That issue has already been tackled with Verified Accounts, and while a few disputes could still occur over Twitter name-squatting (as big brands hop onto the site and find their trademarks taken), it’s hard to see a major legal challenge on the horizon.

By allowing third parties like Twitpic to host images for the site, meanwhile, Twitter avoids most of the issues associated with pornography, copyright infringement and censorship. Compared to YouTube and Google, it would seem that Twitter is a much less obvious legal target.
