It seems like every day there is a closure announcement or a site shows up with an expired domain or hosting suspended. Initially that might look like a bad thing and that PTR is crumbling.
I feel a bit differently about it. I feel that there was intense oversaturation and that fewer programs (especially those with PTP) will be beneficial to the system in the long run.
#1 Wannabe POs without sound plans will become hesitant to open or take over programs.
#2 Members will be in fewer programs and have more time to explore what is being offered by the programs they are in.
#3 Less pressure on 3rd parties, possibly bringing better results.
#4 The POs who think outside the box have a better field on which to grow their ideas.
PTR in many of the ways we knew it is crumbling, but I think those programs and POs who remain will become stronger and better.
