I think Nokia pretty much killed it with the Meego announcement. Back in January the momentum of Maemo development was building up and it was all exciting - even I (not that I am special - just specially lazy) made a few ports and packaged it for Maemo. But after the Meego announcement I just completely lost interest and I reckon that's what happened to a lot of other people. I was excited about Maemo because it finally appeared as if Nokia had decided to push this as their next big platform - and when Nokia left it hanging - well - there's nothing left. For me I'd rather just stick with Symbian until they get their act together.
They're maemo and MeeGo... "Meamo!" sounds like what Zorro would say to catherine zeta jones... after she slaps him for looking at her dirtily...
