There's also different kinds of roleplays. Some people write long green-papered narratives, others just flavor how their characters act and speak.
I've written my share of "roleplays", but unless it's over critical events (religious rites, a royal wedding, the death of an important character, etc.), roleplays for the sake of roleplays tend to bore me. Greater Xavax has a bunch of those if that's what you like.
And some people will be reactive, they are just tired of doing the first steps.
