When it comes to the social web, tags have become an indelible part of the way people connect and interact with each other. It was only to be expected.
As far as Twitter is concerned, a tag ensures that everybody is in the same wavelength and it lets people know instantly whether or not they would be interested in that conversation.
Trouble is, these tags can be a little arbitrary or obscure sometimes. That is why a site like this one is a very good idea: it lets people define tags, so that anybody can know what a discussion or conversation is all about.
What’s more, once a tag has been defined those who use the site can vote on its accuracy, effectively democratizing the whole process as much as possible. To do so, all that is required is an Open ID.
Summing up, quite an interesting service that can occupy an important space indeed. If you are new to the social scene, bookmarking it could be a good idea.
