I'll do the same thing, having too many browser tabs open reading multiple AV subjects. I tried understanding room acoustics in one night... I ended up having to close the entire browser and walking away from the computer for a few minutes due to the overwhelming information I'm trying to digest.
I'm currently planing building my own subwoofers, plotting responses using REW room sim for the two subs, upgrading my main speakers, changing my processor/amp, finishing some remodelling in our main bedroom and planing some changes to the living room to help improve image contrast for my projector. I end up with so many tabs open, made worse if I spot something on the classifieds section of the UK AV forum I go on. I got home early from work today and had lots of things I intended to do, but ended up with a multi tabbed 6 hour browser session instead.
Woman say that men can't multitask...I can, but it hurts.
