based on my musical taste. Good choice to get to know new artists. The only problem is that artists or labels need to fill out those fields, apparently, and that's no good. Many artists are not present on last.fm (meaning they don't manage their profiles), also many albums are messed up. For example, in my case, what is Spock's Beard's Octane doing there? That album was five years ago! (It's okay when it's shown that it's a re-release or something, but just like that…)
That artist suggestion feature has been there for quite a while, but i haven't used it much. If i'd get bored with my library (highly improbable, but still), then there would be the first to look, but usually i don't check out new music just because it's similar to what i already have. Also, it's not perfect. It should be working on a 3-month or 6-month base instead of whole-library analysis, so that recent taste changes would be better reflected. Also i don't necessarily want more of the music i already have a lot of—rather get to know new ones in genres that i so far listened to not that much. (See, in japanese i write in english structures, in english i use japanese ways. S(l)ick.)
The event recommendations did not change, and it's alright like that. Useful, though many events are missing…
