I haven't really done it recently at all, but it's really not that hard (although now that twitter likes are private, it's become a lot more difficult). I used to make twitter lists of every recruit we offer, and then remove them when they commit elsewhere. This created a feed I could check every day to see what they were saying. I also had one for the coaches. It used to be even easier when the following lists for coaches listed their most recent follows first. That's not the case anymore.
This year is probably the hardest it's been since twitter became the main recruiting tool to track our recruits. I used to really enjoy tracking recruits (especially potential transfers), although in the last couple years I've been too busy.
