I check the summit logs too, to see what the latest conditions might be. Often just a sentence or two there is as useful as a photo album someone has labeled as a trip report. And every few weeks I get a PM from someone who saw me in a climbing log, asking about conditions or specifics. It is a good way to let people know you might have some info if they are looking for it.
I don't really see the need to revamp the weighting system of trip reports, if power is not that important anyway (which it isn't, someone's who's power is 200 as essentially as much vote weight as someone who is 1000). It affects very little.
