I'm a bit of a control-freak DM, so I keep a campaign web page with tallies of each characters' current level and XP (XP gets tossed out every time the party rests, so it helps if I keep track... and I need to know how big they are...) and a short session journal featuring the highlights that I remember and any salient plot-points that the party picked up (in the clearest verbiage I can provide, such that even if I'm incoherent when DMing, they've got the info they need to move the story along). It removes a bit of the red herring intrigue from the game, but having winged through several sessions of red herring fishing (we call it "getting a ladder"), I don't view it as a problem.
This worked out really well when the party found an informant NPC and gave him a lot of money -- one of the players jotted down notes about what they asked which I collected after the session. I compared their notes to my script and wrote the parts that they asked about out as a rant, posted it, printed it, and handed it back (inclusive of all of the little details that I hadn't anticipated them asking for, but they did and I was able to tell them that "he gives you an answer that the specifics of won't be relevant for a while yet but they will be in the copy I give you...").
I find that it's a good way to keep everybody engaged in our 3-hour sessions instead of letting anybody go heads-down (worst of all me) to scribe. Then they refer to the web page if something occurs to them between sessions, make their prep notes based on that and voila, we're all in the same parliance again with correct NPC names and everything.
