Two very interesting sites to take a look at:
* Retrievr is the future of “search engines” according to me, thanks to this site, you’ll be able to search and explore in a selection of Flickr images by drawing a rough sketch. It’s still experimental but it’s very interesting!
* Gickr is a service that allows you to create animated Gifs online. There are a couple ways that you can do it though. You can either search Flickr for pictures, use your Flickr account, or you can just upload images to Gickr and create your animated Gif. You can also choose from different sizes and speeds for your Gif. It’s really easy to use and it’s fun so try it out.

Digg, Ma.gnolia, Feedburner, Flickr, Last.fm, del.icio.us etc… How many communities, how many accounts!!!
What about having them all in just one page?
Facebook always have been my favorite one, because of the design, ease of use but especially because you can add “applications” to it (like Digg, Ma.gnolia etc…).
As a result you’ll have all your accounts communicating with your Facebook’s.
It reminds me the way Mac applications works: all communicating with each others.
The links:
Here is for example the Digg application just click on this link and you’ll see how easy it is!
Here you’ll find the complete list of more than 30 applications for Facebook.
Here is the Applications directory from Facebook.
And here’s my facebook account if you’re interested to see the “final result”

If you right-click or control click on the toolbar you can set it to Image Only, Text Only, or both. This is also another way to get to the Customize Toolbar window.
