I've never liked blogging, have never been any good at blogging and never seen any value in it.
In the old days, the blog was the way to communicate your message and have an audience interact with the author.
Then SEO took over the world and blogs turned into keyword spam and the blog churn started. IMHO these days there are many more avenues for aspiring authors or people wanting to be seen as a credible expert in their field. Place like forums, Facebook or Google communities.
If you want SEO benefits, then you are talking about crafted content about a particular subject optimised for a particular keyword. This doesn't have to be a blog, but ideally needs to be on your website so you get the benefit. This can then be promoted via social media etc to try and draw an audience in.
But if grammar, spelling or style is a concern which you may not want on your main website, then social media is a better avenue. It's more relaxed, forgiving and has potential reach if you are talking to the right audience, eg Facebook groups, Google Communities etc.
