More and more Internet service companies are merging, and that means that for some of those services you will need to merge your accounts, or convert one account to another to continue using the service.

One such example is the recent news, "Flickr to require Yahoo usernames", and it's causing a certain amount of friction.

Some users simply don't want to have to use a Yahoo user name to make use of their Flickr photos. Others like the cachet of being one of the old school of Flickr users and don't want to be tarred with the Yahoo ID hiding their roots.
