I'm using Poser 6 now, I'm happy with it. Most of the changes from what I hear in Posers 7 & 8 were more content, a few extra shader options, and a few extension additions. I think people who early adopt (habitually) do pay way too much, and they kinda mess it up for the rest of us to - because the available new (free and pay) content that works well - or just plain WORKS - with whatever version you CURRENTLY have quickly shrinks and soon disappears because everybody who has money to flush down the crapper jumps on the trendy bandwagon - leaving the limited income guys using older versions in a clinch and basically screwed. Thank God most Poser 4 content will work fine on 6 will a little codjolling, but there's no gaurantee that Smith Micro (who in my opinion trashed Content Paradise to smithereens) won't go all dork on us and suddenly pull a new version of Poser out of there corporate butts that won't be able to use ANY past Poser content, and the more frequently people snap up new versions fresh off the drawing board because they have less patience than someone who's gotta pee real bad, the closer that nightmare day might creep upon the rest of us who have enough grey matter to know better - SNAPPITTY SNAP SNAP bros and sisses!!!!
Wait - and you'll pay less and preserve the available content base - snap it up quick - and you have more bugs to deal with - and you'll be a party pooper for everybody else. Case closed.
I can remember a time when Content Paradise, 3DCommune, and RUNTIMEDNA were FAR more community based, and far less profit margin. I think SHARECG is one of the last true community based CGI sites out there, but who knows how long it'll be until it goes the way of the others, and turns into a dump where the freebies suck and become far fewer, you have to give your life story to register, and the community memberships shrink to only a fraction of what they were. Now THERE'S the elephant in the room that nobody likes to talk about!!!
