Haha, you should see my bookmarks... no less than 10,000 right now (probably more) and I export and clean them every 6 months. The thing is they are all quality sites or pages and interesting information that I would like to read or will need sometime soon. I've tried all of the major bookmarking sites and have even planned on rolling my own a couple of times (didn't have enough time to build it out though). 500 tabs is probably an exaggeration, but unless I recently restarted my computer or Chrome so it will update I always have over 100 open. Does anyone know of an open-source bookmark manager that can be self-hosted? The bookmarklet is easy to create and archiving a copy of the site would be a really nice feature (but not required). There are also several scripts to pull out summaries or body text from pages, but those could always be processed later.
