I don't think you are going against the grain, everything you said was fine. If we talk about experiences, everyone does not have the same experience, some people found it to be good, others average and others bad.
Generally speaking Beezy I would say when something new comes along, the first 20 or 30 pages are mostly filled with that gold. As more people get more experienced they point out things they don't like. I do agree the same points don't have to be harped on if they have been given a clear answer. I think Hookbox has pointed out issues that a noob should care about. Some people equate brandables with BrandBucket only, if the name gets rejected they drop it, that is not a good way to go about this imo. 15,000 names does bring about more competition making it harder to get found. That doesn't mean you can't have success on BrandBucket but I personally don't see anything wrong with the opposite side of the coin and exploring potential pitfalls.
There are some people that are flat out wasting money, money that is never coming back, you need to get some kind of proof of concept in your work. If you own 500 M.U.P.S. and no sales plus $10 listing fee, this may not be the niche for you if that happens year in and year out. Brandables require patience but no sales over a multi year period may require reassessing the brandable portfolio.
I try to always be transparent and consistent, I tell people what I use, what I don't etc... I have an account with BrandBucket but with no active listings. For me personally I like and have communicated with Margot several times but I was never a fan of exclusivity, Some of my better Made Up Pronounceables have gotten a lot of offers and I did not want to pay 30% and be exclusive, I recently sold one keyword brandable IntelligentSky.com. That's why I don't have any active listings currently, that may change. I just don't like exclusivity personally, Margot has stated to me that Brandable Boutiques have to be run that way, and that is fine, it is why I have chosen to stay on the sideline, because even if you get an offer through email and then tell BrandBucket to remove, they want a 30 day window where they still get the 30% commission even if you sold it somewhere else.
I write and follow the brandables market so I watch everything BrandBucket does and wish them and all sellers success.
Discussion on what actually happens is the most important thing imo, getting stats would be the biggest help for sellers, because then they could see their name got 20 direct typeins, 3 BrandBucket searches and 1 Google search. That way you know what is going on, evaluate that data for a few months, if direct type ins were the top traffic source maybe you want to pull the name, set up your own lander and save 30%.
Some people may never want to do that, their brandable portfolio is not their day job and farming out everything to BrandBucket is worth 30%.
Again is the juice worth the squeeze ? For everyone that measure will be different.
