Here's an interested ProfHacker post on blogging:

I have done small-scale blogging with Wordpress installed on one of my domains for ... probably over a decade? Various incarnations, various topics--everything from ESL teaching to reading books in translation to, currently, running and hiking.
I also read a ton of blogs and I feel like I get a lot out of them. I use Feedly to collect them.
