Introductions are only boring if you have no imagination to make them interesting or don't have fun interacting people in one of the most principal moments of a story.

This.

Introductions are wonderful things; I love writing my first post in a roleplay to establish my character and set her/him up for the journey ahead. It allows me to show an example of my character, beyond the CS: As most people know that they write a CS and end up playing a character differently. An introduction post allows you to express how things'll truly be going down, and what your fellow roleplayers can expect from you.

Now if you aren't a writer, I guess I get it. Pure roleplayers like to be thrown into the thick of things and don't care much about the path ahead; They just want something to bash their keyboard about. I'm certain any writer would whole-heartedly appreciate introduction posts though, as they are probably the most creative you'll be able to be in some roleplays: Specifically in plot-heavy ones. 

Also personally, it lets me gauge if someone is worth my time: Specifically in 1x1's. I almost fight people so I have the right to write our intro, but occasionally if I'm unsure of my partner, I'll have them do it. Sometimes I'll get something good, sometimes I'll get something that'll disappoint me. And when the latter happens, it is usually a good sign that we aren't good partners, as I'd like someone who is at least somewhat talented: Not someone who just spends a single paragraph getting straight to the point, but spends many expressing their character and how they act in the world provided. If they can't do that, it's not exactly motivating for me to do it. And sure I could stoop down and post like them so I feel like no effort was lost, but...

I'm not that desperate.
