My FileSonic and FileServe have probably paid off by now (I've been uploading my content to there RARed for awhile now--I haven't shared most of it yet, but it's there). Pretty much being able to find and download something from those two hosts whenever I want is pretty fucking cool.
I'd be willing to bet pretty serious money that MegaUpload will never go down. I'm also starting to feel pretty confident in FileServe and FileSonic.
BOTH my MU accounts have paid off, really. I have one I get to let my friends/family use to get content, and I have one account with (now) 25 TBs of content that has all been renamed/organized perfectly.

Work In Progress: Downloads and auto-extracts to "Show_Name..rest of release/encode details" and imports into iTunes with all the show, episode, descriptions, etc. metadata)
Especially for big purists (such as myself) who want to be able to collect and have access to a huge collection of untouched DVDs and Blu-Rays (although I'm the only person I know who does single-link, zero-extraction blu-ray discs) it's nice to have it all online instead of having to fill up a bunch of external drives (and store them, and organize them, and have some system for figuring out what is on which).
