How's my blog?

I'm trying to find out how people like my blogs. Leave a comment. Are they too short, are they just right, anything I should improve upon, should I include more in the posts, etc. Perhaps most important of all, is the information helpful in any way? I surely hope none of it's a waste of time. I'm writing these blogs for two main reasons. 1) to inform people about things they are less likely to know about, by writing topics that are interesting and go well with what people want to read. And 2) As practice in writing.
