The major reason I decided to use Tumblr more and WordPress less is the annoying advertising that breaks up the content on my main page. It is so obtrusive and ugly that I had to do something.
I already had a blog on Tumblr that I had somewhat abandoned. I redid the design, finding a layout that I like. It is simple and basic, pretty much two columns and that is about it. Kinda like a two-column newspaper or newsletter.
It kinda reminds me of the Drudge Report, and since Drudge is mostly garbage these days, I have created my own version. I am not too concerned about traffic and followers. I post what I want, what I like, what I want to keep on file. These blogs and content are mostly for me. If others find such items useful, then great.
