You can’t make it up to everybody at the same day.
There going to be angry people, because you didn’t had time to answer their comment or to read their post.
If you not active blogger, you wont be able to build your blog in few month, it may take few years.
I find out, that shorter posts has more views, more likes and more comments, because in today’s world people rush all the time.
You wont get support if you are not supportive, you have to let people know about your blog, but not by spaming, by reading and commenting only.
