[personal UX/UI review] the power of "Reply" button on review page (e.g. Chrome Web Store)

<case: Chrome Web Store's product detail page>

positive: the existence of "Reply" button on review page

reason: because of the button, the review page can be used as a terrific communication channel: 1. allowing users to answer questions of another user, which reduces communication cost of the app creator 2. working like a CS (customer service) channel, providing the app creator an opportunity to directly respond to eliminate frustrations of users, which may help reduce "bounce rate" of the app use 3. displaying interactions among users so that each thread can be more open and transparent

[personal UX/UI review] thought on displaying product images on websites

<case: product page on Amazon>

positive: Can see how big the items are intuitively

reason: Putting a universally recognized size standard object such as a deck of cards, coins, silverware, etc. next to a foreign product helps viewers' understanding of the product size.  Also, if the product can be placed at a context such as a hand or an arm, that would be a bonus.
