Hello all I plan on using web 2.0 to rank my keyword in my local language. Most of web 2.0 services here are using english articles for the content. I can live with that as long the english content is relevant. But sometimes i have something in my mind and want to write it down in my local language as article for my products. Is there any problem to use english and non-english articles in one web 2.0? Is it natural? Other question: Is it okay if i use english content in tier 1 and non-english content in tier 2?
