The biggest problem that I know of with revshare is that it is hard to convince webmasters that it is better in the long run. Alot of webmasters are barely scraping by, and they have bills to pay RIGHT NOW. They just don't have time to wait for those recurring payments to build up. Yes, revshare can be great to build up big recurring income, but alot of webmasters just can't afford to give it a try.
And many of them just can't understand that one member at a one time payout of $30 makes less money than one member at $15 a month that stays for 4 months. It's twice as much money, but they can't see past one month.
I personally got into webmastering because I was in a bad relationship and had no education, no money, no job and I didn't even have a car to GET a job. We lived in a rural area with no bus system and to take a taxi several miles to and from work with my kids and pay for daycare would have cost as much as I would have brought in. I couldn't afford to wait on revshare recurring to come in, I needed money right away.
PPS is a great way to bring in some income, and once a webmaster is comfortable with their temporary income level, they can switch to recurring for long-term income if they want to.
Of course, revshare is also good to get into if you're webmastering part-time because your job pays your bills and you can build up the long-term recurring income so that you're somewhat secure when you finally decide to quit the day job and webmaster full-time.
