I've seen a lot of top questions from this site recently, and it always confuses me because I didn't know what "ell" was (I thought the English one changed their name at first). The other Stack Exchange sites don't use acronyms, even when it results in a long URL (graphicdesign.stackexchange.com, codereview.stackexchange.com, salesforce.stackexchange.com, etc.).
Since the URL is used to tell people which site a top question is on, I suggest using one like englishlearners.stackexchange.com, so it's immediately obvious what this site is about.
EDIT: I made a suggestion for the whole network to use site names instead of domain names in the hot questions dropdown. If that gets approved, it will fix my original problem. This change may still be useful either way though, since bare URL linking is fairly common.
