Want to go wild on the big WWW, leave your mark for all to see, but don’t know how or want to start hacking web pages? Fleck allows you to interact with pages on the web just as if they were pages in a magazine. You can save your annotated page for yourself, send it to friends or colleagues, or use it in your blog. After using it for about 15 minutes, I think it is kinda cool but something tells me that there is another program that does this on the web as well, but I can’t remember what it is called (anyone?).
There’s a long list of features that Fleck aims to roll out in time, including photo integration, arrows, multi-language support and Pro accounts with premium features. If they can make this a more fleshed out service while retaining the incredible simplicity it offers now, Fleck could grow into a particularly solid contender in the web page annotation space. – Marshall Kirkpatrick
You can start using Fleck right now. It’s a free download for Firefox (IE is on its way). It really is as simple as that, there is nothing more to say other than go try it out.
Update: Other competing sites I know of are TrailFire and Diigo

The good thing about Fleck is that is such a logical extension of the web that when you first start using it you think "of course!" or "this seems so familiar!".
In the past there were similar system like uTok and Third Voice. They became extremely popular for a while in the late nineties but didn't have any protection against abuse. That became their downfall.
