A lot of us have encountered different people from different cultures since we become more open to the world. If the attraction becomes real, how do you deal with it? Religion? Differences in values?

Hey people in here :)
I have a question for you :)
What is so scary about filling out even the basics in the profile and doing it honestly?
I have stumbled upon several, if not most of profiles in here that i've seen that has nearly nothing in them, not even a short selfexplanatory text about ythemselves.
Is really "hi" meaning everything or what?
Those few who really have something in their profiles such as the answers to the basics and a short text can be counted on one hand and one in particular that caught my eye hasn't even been on here for over a month according to the profile itself.
so, is it so bad to write something about yourself or is the "hi" a shortcut because it's obviously difficult to write something that might catch someones interest?
