TagFound.com web services idea (summary in English and in Italian)

TagFound.com

A user's personal account can have many profiles. Each profile has the tags applied to it. The negotiated anonymity could be useful and an optional extra function.

Possible uses

  • This web service could be used as a way for human resources to find humans and to be found as a human resource. The anonymity negotiated is similar to the partial disclosure of information already practiced today in this field.
  • This web service could be used as a purchase-sale of articles or services
  • This web service could be used for every use in which there are human needs of reciprocal contact and find a "relational agreement" on something they have or offer, symbolized by the tags.
