I disagree - I don’t think Twitter is going down a slippery slope. I think they’re making a sincere attempt to make their service as authentic and as useful as possible.
The subtext is that a Twitter username suggests identity (in fact that’s the underlying magic of Twitter) and that the service on the whole becomes less useful as identity becomes fractured.
It may well come to pass that they need to set up a more stringent system to analyze conflicts (e.g. what if your last name and user name were knicks and your twitter feed was not about basketball?).
