Hi! As you asked me to stop by I did :)
1.) i guess it depends on the overall structure of the comments in the post
2.) all of them, more mainstream stuff please!
3.) havent realy taken the time to read the updates so can't give an input on this one
4.) No!
5.) Just start blogging, try to find something interesting, chose from the most picked themes or make something innovative, it really doesn't matter as long as you have the will and fun on it! People will start noticing you're blog with time! Steemit is just at the beginning!
