According to this, I could make some modifications to my chrome recommender extension, bundle a trained model with it, and then classify tweets on the fly. Hmm, maybe, maybe not. I've been more into Mahout lately because I've going to use it for Project Flare.
On another note, I haven't released v0.4 of the Chrome Extension due to a hiccup in Chrome. It works on stable releases, but the dev releases will screw up due to the transitionary period Chrome is going through with IndexedDB, so I'll wait. By that time v0.5 should be out with Reddit recommendations. I sort of can't live without the recommender though, hahahaha!
