I've got weak regex skillz. I'll admit it.
I don't use them very much, so when I do need to, it's nice to know that regexlib is sitting there, waiting for me to come to it with my regex needs. In particular, there is an online Regular Expression Tester that has helped me to look smarter than I actually am on more than one occasion. Sure, I could use a desktop tool for my regex needs (and sometimes I do), but regexlib has the added bonus of having a collection of user-contributed regular expressions that are super useful when looking for ideas on how to implement a certain regex.
And let's not forget the Cheat Sheet ... regexlib is just chock full of regex goodness.
