Something that drives me crazy is that if I have a link to a blog entry, there's apparently no way to jump straight to the blogger's profile, to find previous entries. I should be able to get there by clicking the blogger's name, but that only works when I'm already on the profile page (?!). Also, I differentially can and cannot scroll with my mouse wheel depending on which part of the page my pointer is on. Not to mention that the layout is so confusing and unintuitive that I usually have to click a couple of things before I can determine which link I should use to get somewhere. Part of this has to do with the fact that the blogs are compressed into the bottom of the profile page, instead of the profile page being a link off the blog, as is the standard for blogs...they're blog-post-centric, which makes sense.
They made sure that there were plenty of kewl WotC-brand icons, google ads (so I'm told. I use AdBlock Plus), and but they didn't work on basic functionality?
Count me as another voice calling for the developer blogs to get un-migrated until the gleemax site is at least as functional as the messageboards were.
