I'm interested in thoughts about +tech buildings (and character traits, for that matter). Anybody out there building lots of libraries, +research temples, etc?

Reworking my province building slots IAW Myth's thoughts zoomed my income through the roof. Works great. (A factor may have been the Patch 2 squalor/food tweaks. It's possible that I had settled on some semi-conscious "building rules" which made sense before Patch 2, and then I didn't adjust afterwards until reading this guide).

One constant, however, before/after Patch 2, and before/after reading through the OP here, has been that I haven't built any library-line buildings at all, and very few research temples. I just always felt that there were more compelling uses for building slots. As a result, 240ish turns into the campaign, my overall research rate is in the 120's. I haven't finished out the third tier in any of the six research trees. Each of the remaining tier-three techs are requiring 16-18 turns to research, and I've got enough of them left that it would take something like 150 more turns to completely finish out the entire tech tree.

Is this consistent with others' experiences deep into a campaign, or have I just totally gooned it somehow? Has anyone had success in creating a specialized "research province" or two?
