Website content and member database ids : <p>Why are some websites programmed to start member ids at 1 where as
some websites start off the member ids like 30000000000000000 or even
a random hash?</p>

<p>For example, popular forum software such as vbulletin, invision power board, xenforo, etc have their members ids starting at 1. Then you look at steam for example, take a look at a profile and look at that huge member id.</p>

<p>I've also noticed that some websites use uuids for basically member ids.
Like mojang (yes, I know stay with me). They later on added a UUID to each
account.</p>

<p>What are the benefits of each one? Wouldn't starting at the id of 1 use less database storage?</p>
