Asking for suggestions,, probably not, nothing to do with the deal thread. They can go in buying suggestion.
Asking for more details about a product which was just posted is fine according to me. You can't keep creating new threads every time you want to know about something. Someone posts a monitor saying "this is available for 7k, usually it's 8.5k". You are looking for a monitor, but haven't heard of this particular model. You can totally ask if this suits your needs. If you create a new thread for this, the deal might be over by the time people respond.
Also, it's a free and open forum. Trying to impose too many rules will just lead to arguments. I don't see any problems in discussing on a forum which is meant for discussions.
Also, the options are pretty loaded, especially by adding "a la desidime". If you wanted to put forth your opinion, you shouldn't have done it as a poll. The poll options should be free of your own biases.
