Now I'm not the only one who tend to go a bit douchebag-braggy whenever trying a less popular alternative website, but yeah, that was what I was thinking when joining Mixx. Aaaand it temporarily died. And became Chime.in (which I still got to try sometime... cuz it seems interesting).
Currently using BeritaGue until now. It's the second site made for Indonesians that I'm on since Kronologger (a microblog), but that's another story.
