Others already mentioned chat etc and I would like to just add, Bloomberg is one of the largest electronic trading platform for certain financial products/markets (e.g. many types of swaps)
That's an interesting point and I agree to an extend, but sometimes I do look for mentions of a particular feature or use case, and in those cases a review that covers those points are more useful.
So unless the review cater to me personally by covering those points, I usually prefer a more detailed review (or a large number of reviews/discussions by Googling in the hope that someone covers those points).
In my experience Reddit works quite well, when it works (i.e. when there are people to engage with you)
My current thinking is that you need the reviewers to have their reputation on the line somehow when they review something. There are quite a few options to do this algorithmically, happy to chat if it's something you are interested in too.
I think Reddit works quite well as an effective review site for products from certain brands, and in most of the brand subs maintained by independent mods, you do get a wide spectrum of views.
Spam is automatically taken care for you too (if you ignore the non-review posts).
