@Terry Freedman
Being that you run an ICT site I think it would be entirely appropriate for you to use a pop-up with one question in it for users to click the multi-choice radio button in response to. Depending on readership you may keep it up there for a week or for so many hundred site views.
I would also suggest that if you want to make changes to your blog but are apprehensive about it, that you change one thing at a time gradually. Perhaps left aligning and using interesting bullets under the 'Keep me updated' button, or giving your sidebars decent left and right padding?
For each change you make, draw your readers attention to it at the end of a blog post (once per week?) asking if your readers like the newest tweak - people tend to tell you when they don't like something :)
Could a thread be opened here in these 31DBBB forums to ask for other bloggers feedback to your site and others, as Darren does from time to time for other bloggers?
I am sure that many of us, me included, would appreciate a third parties take on what they think of our 'babies', if done graciously!
