> Instead of automatically tagging topics, I would like the idea of suggesting tags just as similar topics are suggested, but I imagine this isn’t that cheap to have (because we would need to maintain some sort of model/corpus per tag).

A bayesian algorithm would work well here.

To seed it, feed in all the current tagged posts, and let it learn which words in the content of a post correspond (probabilistically) to which tags.
