Peer review on Yit Wei's WA2

Well, this is a well-constructed essay. Statements and arguments are quite clear supported by enough evidence. I only find two places which may be improved. In the first paragraph, one of the argument which is expanded in the coming paragraphs is soly exposed (SRM lacks expericental data), which is a little bit abrupt. It could be improved by introducing other arguments in the paragraph or delecting that sentence and adding a more genral sentence. The other one lies in the last paragraph. "we should only focus on ..." is too absolute. Anyway, it is just a piece of small suggestion. The whole essay is quite good.
