Yeah, I have a del.icio.us account, but I never use it. The thing is, I generally never re-read fics. And if I think a fic is good enough to re-read, then generally I remember enough about it to find it again, if I can't find it, well, that's what sgastoryfinders is for :P.

So instead I have an e-mail draft (well a couple, so that they're separated by fandom) that I post links to along with a description of whatever made me want to read it.

Once I go read it, I just delete it from the list.
God bless the SGA fandom and it's prolific-ness, my to-read e-mail is 40 pages long, so I always have a variety to choose from. :P
