Greetings,
i started the curation of freebies nearly 2 months ago on a service called scoop.it:
If you follow the sources you will get about 30 blogs i check for freebies, not including some SL magazines i use and of course flickr-groups and the marketplace. All together i think i use about 50 sources for this summary on scoop.it.
I try there to keep it more a NON-fashion summary then you will find in blogs. Normally the ratio on blogs from fashion related to non fashion related is about 90:10, i keep it <50 to >50.
The FRITZPAPER: http://www.scoop.it/t/second-life-freebies-und-mehr
Greetings Fritz
