Over the last several years, the UK libel laws have been a strong

consideration in WMF carefully maintaining *no* local business presence in the UK. The legal environment here is toxic for anyone who doesn't have to put up with it.

I've discussed this precise issue (informally) with Twitter's general counsel, and we agree that the exposure for Twitter in the UK is significantly different than it would be for the Wikimedia Foundation. I mean, of course you can libel someone in 140 characters -- we've all seen it happen. But the role of Twitter in relation to tweets is much more like (say) a phone company's role than it is like WMF's or even Google's.

Twitter is an excellent company to put this analysis to the test -- it has the legal resources to challenge a libel lawsuit (or a hundred, or a thousand), and the role it plays as a communications medium is, if not unique, then certainly pretty unusual.

I'd look at legal precedents involving SMS/texting in the UK -- that may tell you what Twitter is thinking.

The risks for WMF in the UK (and, indeed, throughout the EU as a function of UK membership in the European Union) remain pretty significant, largely for all the reasons that Wikipedia is something different from Twitter.
