I am sick of Orkut. It was great at the beginning, but lately, it becomes irritating as it gets slower and slower and I get tens of spam messages every day.
Just when I am fed up with SNS (although Orkut was the only one I have tried), Sun L introduced me to Multiply. Besides the usual SNS stuff, Multiply also provides you with 1GB of webspace which can used to display photos and write all sorts of things, including journal / blog, reviews (books, movies, restaurants, games, etc.), recipes and even stuff you wish to sell.
I have not tested all the features yet, so I have no useful comment at the moment, but the interface is quite user-friendly. According to Sun L, Multiply seems to support Chinese characters. The remaining question would be … Will it become sluggish in a few months, just like Orkut did?
