Okay - 225 lbs, 6'4" (plus) and 32K miles of commuting on Hybrids and MTBs.
I just got a road bike (poor thing, doesn't know what's in store for it - I kinda feel sorry for it's nice shiny paint and drivetrain - we'll see if it's so happy after it becomes another Oxberger commuter special ).
Ten miles into my first ride and I get a flat. The tinyest thorn I ever saw let all of my 120lbs of air out in about 2 minutes.
Now on my hybrid and MTB I had great luck with Slime and other such products keeping the air in until I was in the comfort of my work or home (where I could use my nice floor pump). With the MTB I've had great luck with tire liners - they've kept many a thorn or bit if metal tire cord from working a hole in the tube (and let me use the cheapo $2 tubes from performance).
What options for flat-proofing a road bike do I have on a tiny 23 mm tire?
What do you all do to keep the flats to a minimum?
