People read successful people's blogs, not yours nor mine (had one 15 years ago, no one read that either). So stop wasting time on tweaking the front porch and work on the piping instead.
Occasionally I get an email thanking me for a post, or correcting some error.
Additionally, writing blogs/or blog like articles on one's own site doesn't necessarily have to be directed at growing an audience. I personally think that adding some formality to writing (which might not exist in a diary) and publishing it can produce some useful notes for the author to reflect upon later. If nothing else writing short articles can serve as useful practice in writing down and expressing ideas. Of course there is still plenty to be said about the benefits of pen and paper which people do seem to overlook.
I'd also say that a well kept blog may be more important than a CV since you can actually tell how good you are in your job.
To answer the question: I used to blog with pelican, and now hugo.
I feel that most people crave attention more than they crave growing in whatever they are writing about. Maybe it all boils down to how I felt back then. These days, I read much more and write very little. It fits me at the moment, and I am better for not craving others attention and approval.
Oh well, I'll stick to fountain pens for now. :)
