It's very important that you have a list of blogs related to your niche ready for commenting, writing guest blog entries, linking or whatever your strategy of blog promotion is? I tried to discover some good environmental blogs on google but the results were not enthusiastic.
So thought of posting here at IB. There might be few nature lovers out here so please introduce your environmental blog or environment related blog here-
Mine is Environment About: The Encyclopedia of Environment
Seriously, the list will be of great help!!!
