Birth of a Meme

First there was Flickr, now there is Flagr (via Jack Schofield): do I detect a trend here?

Is this a new -thon (telethon, walkathon, singathon etc.) of the online world? Could attaching the -r suffix to words be the Web 2.0 equivalent of all those Web 1.0 companies whose names began relentlessly with the prefix Net, from Netscape on?

Update: Jack Schofield has pointed that there is also Flockr, and we also have PICTR: any others?
