I am more interested to find platforms where laymen share their pains about items they use.
Users can give feedback for their product which can be used by others to decide which product in the same niche they want before trying every product and then finding out.
I am also trying to figure out ratings (Usability, Support, Value for money) for each product.
* startup ideas...
* to gotchas for devs to think about fixing for their respective apps/services...
* to a study in best practices, or maybe what not todos...
...etc. ;-)
