I use the Twenty Eleven theme, and recently the design of my site has started to fray a little around the edges. It seems likely to me that this is the result of some hasty theme tweaks to allow for the inclusion of WordAds. I realise not everyone will see this as a big deal, but I care about the presentation of my blog.
1. The padding between the top of the page and the header has gone.
2. On image pages, the image area is bursting outside the content margins.
3. I think a bit more care could be put into how the Twenty Eleven 'showcase' pages accomodate the skyscraper ads.
That's everything I've spotted so far.
The blog I need help with is halfblog.net.
