Why are clouds 2.0 better than ordinary clouds?

 There is not much to talk about the usefulness and convenience of the tag cloud on Habrahabr, a cool thing. And her information content is high. Then what is Cloud 2.0 and what is it for?
 In short, this is a multi-cloud that works like this: the user presses a CTRL key with a finger or another device;) presses 2 or more tags (tags) sequentially, the selection is displayed under the cloud or directly in the cloud, releases CTRL clicks on the last one tag or the corresponding button, and as a result receives a selection of articles not by one tag, but by a larger number of them, i.e. The relevance of the sample results is increased.

 Also, I think it would be useful to show a title (tooltip) for each tag of the form “X, Y”, where X is the number of articles with this tag and Y is the date of publication of the last article with this tag, for example: “1471 January 27, 2007. "

With respect and sincere love for Habrahabr, rumkinPasha Ryumkin.
