Thanks for sharing. I know the answer for the following question may differ for the individual, but how long (or how many posts) did it take to find your “stride” so to speak?
I wouldn't say I have a "stride" now. I don't write unless I personally feel the topic is interesting so it's tough to call my writing scheduled or disciplined.
Most of my posts go almost completely unread -- that's fine by me.
I'm in the same boat as you are, but I think if you put yourself out there you'd be surprised how much interest there is in the things you write.
I had a blog post featured in a Ruby newsletter because I shared it on Reddit:
