Baidu[1] is a giant search engine like Google, with a market cap of 50bn, so it's not like this is a pump and dump. I suspect the poster is just a bit 'like that'. They probably put citations in their comments.

Take a look at the services list in that article - they are like Google, Wikipedia, and Yahoo all rolled into one, and dominate the Chinese market.
