I just realised I spelt accounts wrong. Herp derp.
Anyway, I update it almost straight away and rate the anime not long later. It's quite addictive and time consuming. I hate how you can't have more than 5 favourites, though. Unless you cheat the system that is, which isn't too hard.
I tried filling a profile for that out once - it was quite tedious (it is data entry after all). I stopped bothering with it after it dawned on me that its purpose and its standard use case were orthogonal, and I could do without an otaku e-peen measuring stick.
Haha, no problem at all. All though, don't take the anime compatibility thing too seriously. Honestly, it's quite stupid as I've had low compatibility with some people when we mostly like the same anime. Take them all with a pinch of salt, and just check your shared anime instead.
I actually use it to help keep mental tabs on completing my queue and making notes of stuff I want to watch/read, and I find the data aggregation interesting. The latter also being the reason I use last.fm.
