I've used bitly.com or other sites for years - primarily to shorten a url.
I can't tell you how many times I've had to format a computer and lost all my 'Favorites' or 'Bookmarks.' With smartphones, tablets, labtops and desktops, it's sometimes hard to remember which device I was on when I saved a link. I don't really want to sync all my devices together; I just want to be able to find a link when I want to find a link. Bitly.com allows me to save everything in one spot and allows me to search all my links. I can even add a searchable 'note' to a link.
Bitly is a handy tool, especially when it's an extremely long url.
I can't believe I missed out on the possible storage possibility for such a long time! Being able to search my stored links is the best part. Adding my own note makes it even easier to search.
