my "bookmarks management" has been through several stages over the years and it bugs me a bit that it's spread over a bunch of different services :
-at the very beginning, I used normal bookmarks in my browser. But that's not handy if you have several devices to access the interwebs which cannot be sync'ed (e.g. home computer, school computer)
-so I switched to del.icio.us for a short period of time
-then I discovered digg and it's mix of user submitted news and social bookmarking. I used that a lot!
-finally I gave up digg and started using Google Reader, which goes one step further because at it's core, it's actually an RSS reader. I was previously using an RSS reader called Vienna on my mac, but the problem was basically the same as with bookmarks in the browser : it's tough to sync RSS feeds across multiple devices (e.g. home computer, work computer, iPod touch)

now... I would like to have all these bookmarks at 1 place only (preferably Google Reader, but I have yet to figure out a way to import them properly)
