Alright well...
small update:
* diigo is not high enough up the priority list to pay for the archiving bit. Same goes for pinboard.
* NetNotes just looks too cluttered and techy but I recommend to try it for yourself cos it works.
* Evernote's latest version seems to do a reasonable good job of saving full pages now, which I wasn't aware of. I also already was using evernote for jots and small notes.
* I already use Instapaper which I love - it also has a bookmarklet to create plain text versions of pages
Therefore I now capture pages with Evernote, complex pages go through instapaper first. Complete workflow:
Find interesting article > save to instapaper > read > repeatedly useful then save to evernote.
How do I find interesting info?
Feeds that go into Google Reader and then get read by Reeder for iPhone then saved to Instapaper usually (it also support Evernote i think - I should test this)
