So, I have one of these ... things, now. So far I think it's really quite atrocious - still a lot of kinks that need to be worked out. While I can jive with any site that happens to have a silhouette of Ichigo as its logo, I am equally agitated by the fact that it is difficult and confusing to navigate. Everything loads just fine, but from a design perspective of being able to find things, it's a bit much. They need to think up a user console design like MySpace has - MS may be the breeding pit of emo kids and deep internets drama, but if you're going to obviously base your module on it, then take the few good things that it has going for it with you.
That noted ... I am not sure how often I will use this. Mostly I have it to keep in touch with other cosplayers, but I don't plan to be haunting the site. The idea is nifty but the execution is questionable.
