Ders: Good question. Probably because I do know more Halachah than them (and most people). That definitely doesn’t make me qualified though. I also do know the most important thing that a person answering Shailos needs to know, namely when to say I don’t know. I also have R’ Schachter’s phone number. That helps a lot.
(I could explain how several seemingly coincidental situations led to a lot of people having no one else to ask. Of course, everything’s Hashgacha. I just hope that I properly realized what HKBH wanted in this situation. Now that some of these people do have other people to ask, they still are more comfortable asking me, regardless of how uncomfortable I am in being asked. But I don’t think I should put those details out on the internet.)
