Does anyone else have a "maybe later" list they never actually touch?

I have a habit of seeing something cool, telling myself i will check it out later, and then completely forgetting about it. It is not even an actual list, just a vague memory that i saw a neat tool once, with no idea what it was called.

The annoying part is knowing there are probably a few useful tools floating around in my head that could help me right now if i had just written them down.

How do you handle this? Do you bookmark things, drop them into a quick note, or just let them go and trust you will run into them again if they are actually worth finding?
