In several things that I do, I require some form of randomness (for example, secure primary keys for databases, with almost no chance of collision error). To do this, I use your site to create them. A simple generation of numbers between 0 and 35, and then change them into their base-36 equivalent, however long the sequence needs to be, and you have an virtually unguessable primary key sequence. You can’t guess what the next key in the sequence will be. Very useful for keeping people from being able to hack your customer list and finding out who does business with you (they might be able to guess one, but the next won’t be sequential, so they would have to start all over again to find the next). I also use it in my writing, to generate datasets for locations and people by assigning integers to various items and using the site to pick the ones that apply.

I am a teacher, and part of my student's grade is based on an in-class response to questions. I noticed that on some days, I was calling on the students who usually don't have the answers, and then on other days, I called on the better students.

To solve this, I produced a truly random class list for every class meeting. Now I don't have to think about who knows what, I just read the next name in the list.
