My biggest gripe branding-wise (apart from the name choice itself ) is that Maemo 6 and MeeGo are not interchangeable. MeeGo (from what we've been hinted) is a much broader thing, more of a family of interwoven platforms and technologies than a particular implemented set (like Maemo 6). I even find it hard to explain why Fremantle (having official Qt4.6 support) is not Meego in the same way Harmattan is.
