In a nutshell, Taggable is a new service that lets you tag people like you do on Facebook everywhere else. For example, you can use this service to tag people on Picasa or Flickr and create content that is instantly associable when a search is carried out.
The way this system is activated is quite simple, since you just log in using Facebook Connect once you have procured the provided bookmarklet.
Of course, people can untag themselves if they don’t want the connection and the link. They can even block the service directly if they don’t wish to have anything to do with it at all.
The true potential of a system like this one, though, lies beyond individual users. This service could be employed by companies that want to launch any marketing campaign and who want to reach out to punters more directly. Besides, Taggable is something that bloggers (not to mention photobloggers) could easily milk. After all, they can use it to include faithful followers into the blog’s content as extensively as they migh twant.
