Good post.
My presence here ebbs and flows based on my personal needs. When I first came here, I was confused and scared about becoming a "full-on" CD. I learned a lot, made a few friends and enjoyed my awakening.
But having an encouraging partner negated a need for much ongoing support. There's only so much you can learn about makeup, dressing, mannerisms and accommodating crossdressing into your life. So my visits became much less frequent.
Then there are times when I'm lonely or have issues which only fellow CDs can relate to, that I return. And in returning, I inevitably get caught up in the stories, the drama and the current events. And so I stick again.
I think the answer lies in your personal loneliness, if I may say that without negative connotations. If you're isolated in your crossdressing, I believe you're much more likely to seek a refuge such as this.
I am not.
I am out to many people. I have regular places I hang out, in the "real world". I have friends who accept me and love to go out with me. I have an SO that loves me the way I am and does not impede my dressing in any way. I have no need to commiserate. I can express my fears, frustrations and successes with people face to face. And I doubt anyone would argue that doing so is not infinitely more enjoyable than doing it in a forum to digital crossdressers.
But please don't misconstrue my words. I do enjoy this place. It serves a valuable purpose. I have no intention of making a final departure. But not all of us need it as much as others.
ETA:
I agree with the comments about repetition. How many "I told the wife", "I shaved my legs", "Am I passable", "I went out the first time" posts can we read without being bored? I realize it's exciting to the poster but I've read dozens and they run together like colors on a palette.
