To avhaben –
My concern is not about those people who discuss halocha for the purpose of asking sheilos in a more knowlegeable manner, and for those who desire to increase their Torah understanding. My concern is for people who use Internet forums in place of a Rav. Even when all information is quoted accurately, p’sak from the Internet is prone to error. Practical halocha depends on numerous variables. Gedolei Yisroel often advise people to ask a local Rav (who may not be on their own level) – as familiarity with the details and circumstances of a sheila is very important.
