Let's be honest. Most people have no idea what an algorithm actually is, so you can frighten them by saying that you're using an algorithm.

An ALGORITHM is simply a limited set of instructions used to compute something.

So, an algorithm could be:

1) Take the relay the user typed in and find events (json files) from that relay.

2) Return the events as an array (ordered collection of events).

3) Find relevant events for this type of client.

4) Use the events to customize the client and define what to display in the feed.
