Matt Cutts from Google Talks About Static URLs with Mod-Rewrite - Recommends Static URLs
In the following video, Matt Cutt's talks about using static vs. dynamic URLs.
He says that PageRank flows to dynamic URLs similar to static - however, dynamic URLs can definitely have too many parameters.
He recommends using 2-3 parameters at most, and avoid ones with numbers to prevent the search engine crawlers from mistaking them for session IDs.

Notes on vBSEO
- Matt says if you can use mod_rewrite to create static URLs, you should do so as it is a "very good way to tackle the problem".
- With a 5-minute installation, vBSEO will completely convert a vBulletin forum into static URLs, eliminately all URL parameters.
- With vBSEO, you get not only static URLs, but more importantly: link consistency and consensus to further boost PageRank.
- mod_rewrite is a complex technology. Do not trust your SEO to a do-it-yourself, non-supported hack.
