It's a delicate problem. To play the devil's advocate, many manufacturers (I don't care about vendors) don't speak the language, let alone have time to busy themselves with fora. They could get badmouthed without even knowing. And it's happened before, elsewhere more than here. I personally appreciate the fact that SRP staff are protecting manufacturers. This comes at a price, of course. But a well written negative review on Google reaches a far wider audience than one here. Many people underestimate the power of Google reviews...
When we built the Wiki, the idea of the team building it was to screen the existing content, ie analyse and assess it, then have the results peer reviewed. It took months to build, and some parts are still lacking. But overall, I'd say that it's the single most objective source of information available, not least because up to 25 experienced users reviewed each page.
There are some grey areas, though, most notably honing. To take an extreme position, pasted strops and maybe a natural hone have served European shavers forever. While experiments with high grit hones gather a lot of attention here, they are laughed about in the German, French, or Spanish fora. These fora, of course, have their pet subjects, too. Such as pasted strops :) But the Wiki has all the basics firmly covered. I always advise beginners to peruse the Wiki, then take an informed buying decision, then learn to shave, and only then use the forum proper. There is such a thing as too much information, and separating the wheat from the chaff takes a fairly high amount of experience. Also, withstanding several of the biases mentioned above takes a lot of experience. XYZ razors aren't the holy grail. There is no holy grail. There are hardly any bad soaps, and the best usually aren't. And so on.
It's not rocket science. Rocket science is just complicated, and almost everyone can learn complicated things. Shaving is complex, and mastering complex subjects takes lateral thinking, keeping an open mind, and a very, very liberal dose of Ockham's razor.
