A blogger-friend of mine once told me that it was totally liberating to be blogging anonymously. She told me that she had (probably still has) a blog where she rants about life and where visitors comment and even debates with her on some of the issues she wrote about.
I attempted to blog anonymously before but blogger-friends told me that I have a distinct way of writing and one can easily recognize me through it. I guess anonymous blogging is not for me, eh?!
If you want to rant about stuff either in your life or your country or life in general, I suggest you go for anonymous blogging. It will afford you some semblance of privacy needed to not only protect your identity but also to protect some people you might be blogging about.
