Noticed a bug on www.edukado.net
If I try to find people specifying a level of their Esperanto, no people are found: http://edukado.net/komunumo/uzantoj
If the website solves this problem, I will consider www.edukado.net the best social network for Esperantists.
Unlike www.lernu.net, it has a map of Esperantists.
Unlike Facebook, it has a map of Esperantists, GUI completely in Esperanto and possibility to specify your level of Esperanto.
Unlike www.esperanto.com, it has good search of members.

But so far, www.lernu.net remains the best Esperanto social network.
