Smartys, the link you pointed a couple of posts ago explains it kind of straight forward.
I didn't want to be trying to make a point out of this, my intention was more sharing this information with punbb users.
I don't want to stop anybody from using sitemaps, i am just sharing my experience with them. None of us know know how does google handles it's data. My experience with google sitemaps was bad, it basically made my traffic go down, and i think this is very likely to happen to other people.
On the other hand, if you are satisfied with sitemaps and they actually brought you traffic, of course you have no reason to drop them.
Liquidator,
Sorry, i don't have time to put effort on that at the moment. But, yep... that would be cool, there's already a minimalistic view, those would be the next step for a full featured ( from the user perspective ) minimum look punbb.
I got reminded that punbb outputs valid xhtml, i wonder if it wouldn't be beter if someone release a flat style instead. I can't think of anything that makes that impossible. Maybe we better wait for the new markup on version 1.3
