Most blogs would accept comments if bloggers can understand what you are trying to say. You have to add to the discussion and not just say 'hey cool blog, thanks for sharing'.
what is this job i could not understand you. i am blogger and have 3 blogs this time.tell me what i will have to do.
I think you aare asking how to make comment on a blog. Read the content and sincerely make a comment. It will get accepted.
Caution : If you open and no protect on comment for blog. You will get spam very much and get large data without benefit
if you want to create blogs go on blog releasted sites like wordpress and blogger, make blog, post there and comment there sorry but your english was not understandable
