It is a constant source of amazement that the reports posted on WGs' AW sites are written in such lyical and glowing terms whereas even the most exciting reviews published on here are so mundane.
I don't agree with this viewpoint either. If you mean the full field reports, then I think you will find that people only write them if they want to curry favour with the women. There aren't many unfavourable ones. What is more, AW asks you to go into detail about what happened. So you mostly get a "lyical" description of the meet. (For the record, I've only written one, after which I decided they were a waste of effort.)
A review on this site is more balanced, and not afraid of telling it how it is.
The short feedback on AW is an even bigger waste of time. You are restricted to the length of a post on Twitter, so what you get is totally superficial. I may post something as feedback as a courtesy, but that is all. If I wasn't impressed, I don't post anything, but I will review here.
