Bryan, I think it's quite obvious Kristin's comments were directed at those who change rep job every 3 months like clockwork; I can't see why you'd even remotely be offended and so defensive unless you're insecure...
Here is my (generalized) breakdown on why reps change companies (breakdown doesn't include reps who keep their jobs long-term):
75% - Hired based on promises of affiliates/sales/rolodex they bring with them. Fail to deliver. Moves on to the next company who buys their "hard sell". Rinse and repeat.
10% - Can deliver, but are loyal only to the almighty dollar and will move along for a few extra bucks. Often backfires on them when leaving a stable company, for a fly-by-night operation throwing cash around.
5% - Company folds, usually not directly related to rep's performance but due to mismanagement and overall short-sighted business sense.
5% - Decide to start their own company/venture. Some succeed, most fail. After failure, they are back to begging for a rep job.
3% - Deliver, but are not kept happy where they are. Differences in company vision, conflict with ownership, failure of management to get stuff done rep requires to do his job, lack of growth, no support/tools/conversions, etc...
2% - Other.
Seriously, if the first kind of people sold their product a tenth as well as they sell themselves when seeking a new job, they would all be rich
