I agree with Leni for the most part, the time.
Though it's already 10pm for GMT+8.
It's not my problem but some people are averse to having people in the US and countries in/around that timezone during their WoE. A lot of people actually voted for Friday and some of the reasons to why was to have the Americans busy at school/work, because basically, WoE active Americans outnumber the WoE active Europeans/Asians.
Having WoE on Sunday would mean more people, for me this is more enjoyable, but I know some would not like having other people on their WoE.
