Want to know how many bookmarks/favorites I have? 1693, that's how many. Most of them are sorted excruciatingly well, but I keep bumping them along from computer to computer and it's kind of overwhelming.
So when I saw this program, which goes through all your bookmarks and finds dead links, on Ask Metafilter today I had to try it out. And it worked...found a LOT of dead links...but now I can't figure out how to transfer that knowledge to my actual brower. I only had a few minutes to look at it, so I'll give it another try soon.
