I am reviewing iteration 3 of whereismycaffeine
Strength:
Layout is great as always. Idea about adding specials/coupons is great; it will give another reason for customers to come to your site instead of searching through 10 other sites to see what specials each site is running. You can maybe have an additional section of the 10 top rated best coffee shops, etc for future iterations.
Weakness:
It would be great if you guys actually buy domain to have it running. I can see it being used by local community (coffee store owners) to get there name and reviews out.
