You title your post "The Art of Blogging.  I think you have caught a very important concept of art and performance.  If you put yourself out there and do a good job, many will appreciate it (silently as well as by giving kudos) others will find they need to try to "critique" your work.

I really got a warm fuzzy feeling when I read most of the comments on your recent post in Bulgarian.  Your loyal readers actually want to help you improve.  In other words, on top of your tutor, your teacher and your two students who help, you have a whole bunch of native speakers you can ask questions about how Bulgarian "works." (And how to spell check - face it you are a bad speller in English, why would you be a good speller in Bulgarian?)

I think you do a remarkable job of being willing to be honest (but then I am your MoM!)
