Also, a major fail IMO, the share buttons are covering the first paragraph of text. This being the first written content visitors will be looking at, you better make this readable as most people aren't as patient as I am and will not stick around...
If it was a case of 2mins reading and you still have no idea then that is certainly puzzling.
You'd definitely come across more professional when taking criticism to heart rather then getting all defensive.
Content certainly always needs updated and every rewrite can make things clearer. Equally though if critique is given, if it can be more direct to specific parts of the content or questions raised that can facilitate a response to help drive understanding, it can provide much more help in making things better.
If you note, you mentioned the share buttons overlapping the content on the left. This bug has been fixed, so your post itself has achieved the required result.
