I used to (for a few short years) be one of those that shunned the kickstand as being dorky or any other slang. As I've grown and my tastes in bikes have changed, I've come to realize that for a lot of my style of riding, that a kickstand comes in pretty handy. It's pretty easy to find something to lean a bike against normally, but not always.
In some places, such as at big bike events or especially my garage, there just isn't enough leaning space to lean my bike against. Kickstands can also sometimes even be useful at bike racks that are too wide. Another solid use for the kickstand is when I tow a trailer. It's very nice to be able to use the kickstand to prop the bike up just about anywhere.
