I'll be completely honest, it's 2:35AM and I only barely skimmed this, but I got interested around the mention of cutting down Facebook and Twitter to Fluid apps and blocking pretty much everything.
One of the main reasons I avoid twitter (other than being bad at it) is that there's no way for me to stop myself from hunting around it. If I was restricted to putting content out only, and not absorbing it (which sounds like it defeats the purpose of having twitter, thus why I don't use twitter), I'd probably be more likely to use it.
