I love tags more than categories :) Would be awesome to see this in S2 soon.

This has been requested before but in a more generic way so you can use it on any field, not just tags.

I'd like this extension too. :-)

Would be awesome to see this in S2 soon.

Do you mean weighting items in suggestion lists as they appear in the admin, or the ability to create tag clouds on the front-end using the method MrBlank linked to above?

The latter is being implemented for RC1 as per Alistair's idea, but I hadn't really thought about the former. Now that you mention it, I think it's a good idea.

any news about that tag clouds?

Take a look at this topic, it might help!
