I wholeheartedly disagree, recommendations are NEVER tolerable. As a long time SO user these types of questions are rejected wholesale across the platform and provide a very disjointed experience.
Additionally, allowing recommendations provide ample opportunity to "Game the system" and manipulate a potentially (but not yet) valid source of information.
Common exploits, the easy ones:
- Promote/shut down posts based on affiliations.
- Use the SE for free "trust" in SEO as well as referrals and other easy system gains.
- Fine line between promotion wrapped in questions and legit question.
- Data farming and/or product research at the expense of the users.
- The list goes on...
I was excited to see this StackExchange leave Area 51 for beta status. My excitement comes from the unregulated and wholesale corrupt nature of model aircraft. HobbyKing, notorious for stealing designed, owns the largest forums an data mines for marketing and trends. GetFPV and others all run a slanted information platforms.
I think that recommendations and "price checks" are too slippery of a slope and the leadership of this SE should be put in question and the SE reset. My experience is quite broad in this field and never have I seen such a toxic culture as model aircraft. Decisions of this ilk are poison and provide a huge disservice to the users and spit in the face of SO culture.
Keep brands and cost out of the discussion and keep it professional.
