First things first, Great work on the blog Onimua, the time you put in as well as the effort really shows and It's very much appreciated. Im personally thankful for that, excellent job.
The one and only thing I don't like that was added to beta 3 is the placement of the "about Author" being placed under the blog entry. It clutters the area I feel and it looks very odd having blog entry >> about author container >> comments. It's a stacked layout that I really think you should consider revisiting. I (for now) moved the html so the "about author" sits on top of the blog entry but i feel this even is a temporary solution for me. I personally think it looks better on top of the blog entry
As seen here but have you thought about having the about author as a block situated on the right hand side on top of the other blocks? You could actually integrate the about author container and add it into the <div class="secondaryContent"> block or simply remove the <div class="secondaryContent"> block and create a custom about us block?
That said, and overall, I'm really liking the improvements here and customising it is a pleasure. Excellent update, excellent add-on great work Onimua.
