I am a developer at heart, and as a developer I love acronyms :)
When ever I am referring to the site, I find myself unsure what to call it. So I end up typing Salesforce Stack Exchange.
What I am proposing is an accepted acronym for refering to the site: SFSE
I don't expect it to get much recognition outside of the stackexchange, but least on the site I can use SFSE and people will know what i'm talking about
I have written this post to elict discussion and hopefully if there is a consensus, a post to link to if someone enquires what SFSE means
