Thanks Margo for the excellent insights. As a diversity trainer I would add two thoughts. 1) Techies often aren't 'people people' in a warm and fuzzy way, and they get a bad rap for this. Look closer and you'll see guardians and loyal work horses who value team effort over individual attention. Acknowledge this.
2) Your advice about toning down is critical. High emotions or unrestrained, 'open' body language can illicit two negative reactions in introverts- they're terrified or think you're nuts. At the very least they're in a uncomfortable zone, and your chance of communicating well is diminished.
