A very interesting
Google search directory has appeared - some kind of a hybrid of
Wikipedia and
Flickr which makes it possible to carry out more effective information retrieval.
Of the merits you need to note the presence of screenshots, tag clouds, nice interface, “correct” (readable) links ... The addition (search) of new sites has been very cleverly done.
The project is in the process of closed beta testing and for authorization you need an invitation from the developers, if you have one, you can enter
here .
In general, very interesting.

UPD: It looks like this is more than just a directory. At the very least, this is a very well structured directory, with support for keywords (tags), support for RSS, and integration of content from related sites.
