Users should never let their profiles lay dormant for long periods of time either, since profiles should be updated periodically to show ongoing activities and changes in a person's life.
Remember that extremely long profiles may not be read by others and can appear to be quite narcissistic.
After compiling the profile, it is very helpful to have a friend or two read and give their opinions about it before posting it to the dating chat site.
When a user is satisfied with the final draft, the profile should then be posted to the selected online service for possibly hundreds of people to read within the first week.
Succinct, accurate and entertaining profiles will undoubtedly receive the most hits within a community.
