From the colors, layout and fonts it looks quite outdated. Not the most appealing colors. Dark has been out for some time. The brown, well, we don't want to say what that looks like.
Side bar text, so much italics, makes it harder to read. Odd to have iphones for sale in the sidebar. More line height would be nice too. Gotta remember there are quite a few older people in IM. Never hurts to make it readable for every one. Need to have a much bigger ad for studiopress, that one probably won't get many clicks and it's pretty tough to read the text.
Why the meta block in the sidebar? Serves no purpose to your visitors. Be more profitable to replace with an advertisement. If anything put your RSS links in the footer, just for the search engines anyways.
You don't really have images for your posts, just colored graphics. Images instead could make your site stand out more and it could be more interesting. Plus more visual if related. Pinterest proves we like visuals.
Post titles are kind of blah, not very click enticing. Obviously you could use some comments, at least for social proof. And I am sure you know you need to go out and get them, they sure don't come on their own, even when you ask on your site. More importantly, I did not noticed any call to action to comment at the end of your post, to encourage them, bug them to comment. Sometime you need to tell them what to do. Not too difficult to get comments.
Social buttons at the bottom of the post could use a call to action as well. Please click, please share, whatever. Kind of on the small side too.
On the main page, some of the post spots, part of it is cut off, the comments/read more button.
Of course just my opinions
