I received an e-mail from a person ... "Timmy", with compliments on my content on SN. While I appreciate this note, ... I'm a little suspicious. It kind of seemed like a spam / mass e-mail message.
My e-mail address is available publicly (e.g., on my blog posts, and on github) so if this was an authentic, personal, note -- then this person could easily have found it. But there's just this hint of doubt in me. Are there others here on SN who have received such an e-mail?
