Seriously, I think I will go back to the old school word document for storing stuff, you can't trust services like this to last. Does anyone have a recommendation of a paid alternative that won't close?
"Pinboard also offers a personal web archive, at a cost of $25/year. Users who choose archiving get a permanent, cached copy of every bookmark they save, and can search the full text of their saved links. (The one-time signup fee counts towards the first year's subscription.)"
Not sure how much more of a guarantee of permanence you get from them, but the fellow behind Pinboard has a great track record of business model innovation.
