Some weeks ago I've asked a question in this site and when I tried to mark an answer as accepted I noticed something odd: Both of the answers I got were quite helpful and I followed guidelines from both of them so I'm tempted to mark as accepted both answers, but I cannot!
This problem made me think about this site and I realized that it does not (and should not) work as other Stack Exchange sites:
Due to the type of questions that this site gathers, many times isn't appropiate to accept answers quickly: i.e.: an answer about a diet might take weeks or months to check if it worked... even more than a year if the user got different valid answers and tries all of them.
Also, the valid answer for a particular user might be a combination of two or more answers!
In other words: while in other sites the user can check if the answer was valid in a timespan of hours or days, in this site the user might need weeks, months or years to check the same. Also, unlike answers on other sites, in this site the answers can be partially valid or more than one different answer can be correct at the same time.
What should we do as users on those situations?
The questions on this site are very person-focused, so even if two users ask the exact same question, the answers might be quite different depending on the user phisical condition, age, sex, health or other factors.
In other words: unlike other sites, two users asking the exact same question might need different answers. That's a pain for other visitors looking for information and also a pain for the colaborators trying to answer questions, is there a plan to address this issue?
