last.fm's neighbour system needs time (to be understood)

Update 2011-04-26:
strangely cantonese_opera has with 3 plays for just 1 artist already 50 neighbours.
The library just contains 14 artists which is e.g. a small subset of . There are other accounts which are also a subset of the chinese opera and have way more plays and artists in library than this account.
Perhaps it's some internal caching problem @last.fm?




original journal article:

see Ash_211 (1 play only, 9 artists in library) and has already 50 neighbours
see baltazarmolina (0 plays, 17 artists in library) and has 2 neighbours


I know of at least 4 accounts which have 100-400plus plays, much more in total artists and they have after 1-2 weeks still no neighbours (ask me, and I provide you the details, e.g. 1 or 2).

Perhaps it is that there is no one around with similar taste?
Doubting this, I am at least their neighbour since my compatibility is pretty good (and from what I know there is definitely more than me as neighbour).

Is it a time factor?
Since baltazarmolina's account exists April 2009 + Ash_211's since Nov. 2010. Perhaps they had also at begin no neighbour?

I have recently the opinion that new accounts should have soon a neighbours list generated. I mean give the new users a place to start. Ok, they can play tags or similar artists or mix radio and such, but you know how it is: finding a good tag can also take time, similar artists often works bad for me(, not sure how mix radio would work for a new user)...

Well, the neighbours list should be good, so creating a bad list is also counterproductive :-(
A dilemma...
How about giving the user a feedback possibility?
If the user does not like some of the neighbours, she should be able to click somewhere and the system provides some other so-called neighbours. This would not only benefit the user but all users and then also last.fm

Work in progress...

    That feedback possibility is something I thought of before. If you think a user shouldn't be in your neighbours, then you could click an x like you can with the recommendations. That way last fm could feedback on how well their algorithm is working and how to do it better.

    Simply because of the variety of music you listen to. Those guys you mentioned first only listen to chinese opera.

    Thanks for your feedback, I've added a table above to illustrate this better (sort criteria: date). My expectation may be wrong, but I expect at least Chinese Opera as neigbour (because it has all the other variants), perfectly also me also + ideally I know 2 other users who I've seen while adding songs fro the above users. The last two accounts in the table are Korean music flavor: gugak incorporating all from haegeum. Well, my expectation as human is probably not same as the last.fm-system's, but well...

    I must try the group artist matcher for some new accounts with artists I get by this tool - let's see...
