KeyF11 can be defined as an online bookmark manager that will let you organize you favorite sites in a very dynamic way, as you can not only store them and visualize them as thumbnails, but you can also add notes such as “This is where to look for new web apps” and “This has a lot of original information on movies directed by Tim Burton”.
Upon signing up, you will receive your very own KeyF11 URL, and by sending the link to others you will effectively be sharing not only your favorite sites in one fell swoop – you will share your insight as far as they are concerned by way of the notes that you have created and attached.
Note, though, that you are not really sharing just everything. For example, you are not sharing your private panels – these are password protected and hidden from other people’s sight.
As a web tool, KeyF11 can be used absolutely for free. I have already seen quite a share of applications that do something quite similar to what this one does and I have no reason to be over-enthusiastic, but I encourage you to visit the site and determine where it does stand for you in person.
