most here probably want there to be as distinction between the 2(including me) because their personal identity is tied to being a geek. They see it as a badge of honour. Being a geek to them(me) means applying yourself to things that are important/interesting without caring if it's cool or effects your social life. However language doesn't work that way. So our(my) aspergerness gets lump with all. So even though i spent my weekends competing at ski races since i spent weekday excelling at math, programming, watching syndicated Star Trek, and generally making little eye contact and mumbling to myself. I get lumped as a nerd/geek with anyone that watches star trek and lacks social skills.

No, there's no real consistency in what people see the difference between those two being, or even in which, if any, has the more positive (or less negative) connotation.
