Minimalist community script

Hey guys,
this is my first post here and I’d need a tip… After testing a plethora of demos my head is spinning %) and it all seems to lead nowhere.

I want to build a little community, in a field of chaos (activism). The plan is to accentuate structured “user info”-pages, in order to reduce the ideological crap. It should offer a basic (text-only/no WYSIWYG) blog with comment function, and searchable user lists (interest categories/location). - I’m a 90s-type, what I could find online were mostly Facebook-clones for video chat… .xX.
