Typical web browser bookmarking:

Add to Favorites
Never visit that site again because favorites list quickly became too big, unwieldy, unordered and unmanageable.

"Now that I use iFaves as my home page, all my favorite sites are on my browser's start page, and everything else is essentially two clicks away. And one of the things I like best, is that when bookmarking a site, if I want to send it to someone else (which is something I do a lot), it's one extra click on their nickname, instead of what I used to do, which was copy and paste the URL into a new email every time." -Ian Donen, iFaves.com co-founder
