I see your point, but no one would convert to Islam by seeing your religious salutations in your questions. So I don't see your point at the same time!

This is an SE site and we *have to* follow the network policy. There are some minor differences, of course; but I think religious salutations are completely unnecessary and some people might find it annoying since the site is not specific to Muslims.

[I brought it up on meta.SO][1], most people think it's up to this community to make the decision.
