I've only been on this site for less than a week and I was almost sure that I read an identifying comment the other day. The thing you have to realize is this: In most instances the so-called "identifying comment" is by nature exclusive to those few that can relate to it. For example: If you come from a shul whose Rav always uses a specific saying (whatchamacallit?) and when giving a nimshal always uses the same nimshal; if one were to use both the nimshal and the saying on this site, he would be setting himself up for a partial ID. However, this can only be possible if there is another person from that SAME shul that is an active user of this forum. Therefore, if one were to see something that he feels is an identifying feature, no matter what it may be, he has to realize that it is only relevant to himself. One has to realize that each comment he makes will not reveal himself to the general public (unless he comments gregariously), rather it may open himself up to a few certain people that he is already close with. This being said I do feel that if someone were to ID me, I would be terrified, since as I am single and like many have stated about future son-in-laws, the ramifications are too enormous (I guess the list of girls for me would be narrowed down to all of your daughters
).
On the other hand, if someone that was really close to me would ID me, I would be apprehensive at first, than afterwords I would probably go out with him to celebrate our struggles and attempts at stopping our old ways.
