I did not have my e-mail for a long time (for the same reasons that you mention and that I use my work address). But I eventually decided to add it, I was convinced by others on this site that said that they did not have a problem. I have not received many e-mails because of it. The only negative experience was virus related. There was a week when I used to receive many warnings a day that someone had sent me an e-mail with a virus, since I did not recognize the address and since this is the only public place I have posted it, I am assuming that it might have been someone from here.
