I have similar feelings as the other commenters - it needs features "now". Some missing functionality compared to the old version is a normal thing for a short while, but this is taking way too long.

I'm willing to throw some money at pumpio to have it on par with all features that statusnet had. Especially #tags and !groups and @mentions (including simple formatting for #!@, not the html that we have now). How about a kickstarter or something?
