I understand why SX might be chosen over SE, since SE is already a famous acronym for Stack Exchange, but I don't understand why SE and SX are both used for Space Exploration.
For example, in the title bar in the browser, both SpaceEx main and meta use "SE", but the chat uses "SX".
On the user page on main, the meta user button uses "SX". Same for the main user button on meta.
Is this an oversight?
