Google reports that on my site it found 31,000+ duplicate title tags. I got a bit confused at first, but then realized, "Oh, the IPB... " - the <title> tag has the same info no matter which page you're on inside a topic (page1 of a topic will have same title as page2, page3, page4, and so on)

So, to make things more descriptive, would it not be possible to take an excerpt from the first post in that topic, and stick it right in the title tag?

(At least it'd get rid of all the 'errors' that Google is reporting about my site)

Don't think an excerpt would be the best idea...A "- Page #" on the end would be nice though.
