That’s sharp, engtech. I particularly like the clean sidebar. The slashes in the title (//engtech) are a nice touch that communicates your technical side in an artistic way. I would recommend you downsize the main menu titles in the masthead, though, or build some space around them, or both (home, articles, opinion, blogging, links); they look cramped. Finally, have you considered following through on the “slash” theme, for the menu heads as well? By that I mean:
/home /articles /opinion /blogging /links . . .
