Which plugins do you use and how did you do that?

I looked around and didn't see it... I think it would be great to have two regular topics that your staff or advanced website designers contribute to, one that simply lists the plugins they currently use on a given website (there used to be a plugin for that). The current forest of plugins to do any one task, all with conflicting and misleading names, all with inconsistent levels of support and code quality, is an amazing hazard to even the best admin, not to mention all of us good but part-time admins.

And another that briefly describes the tools used to create the design/feature of a given page (like this one). Not a full tutorial on how to do something, which by its nature needs to be somewhat generic, but just a short list of theme/template/plugin/css usage, just enough info to give a reasonably talented admin a path to follow.
