You can pick what you want to write about, as long as it is in decent language and you know what you are talking about. No extremes please. I am currently recruiting many writers. It is for a news portal and I am already getting decent traffic. As the website is a start up on a shoe string, I can not offer any compensation for this currently. But if you can commit to daily postings, I can offer you a 60/40 share of the Google Adsense revenue. Meaning you get 60% of the revenue generated by your posts. If you don't have Adsense, I can show you how to get it. So, please send me a PM describing what you can do and a sample of your writing.
