Fran Crimi is a regular contributor. I believe Ray Martin has posted here, Keith McCready, Mike Dechaine, but I don't think any of those three have contributed regularly.
Most of the pro, semi-pro, Hall of Famers, and retired pros post on Facebook on a daily basis. It's fun.
What I enjoy most about the interactions with pool peeps on Facebook is that I get a chance to know what's happening around the world in pool, as well as keep up with the pool smut.

This forum used to be the go-to place, but I do believe FB and other social media avenues have taken over. For example, Mika posts photos all day long and shares his thoughts on various topics. He's on Instagram, Twitter, et cetera. He's a hoot! :grin-square:
The new kids on the block -- Justin Bergman, Sky, Oscar -- all of them are regulars on FB, and it is great reading what they have to say about pool in the year 2016.
T-Rex travels the country and attends many regional tournaments. Go to his page and find out what's happening and where in pool tournaments in the States, and then there's the action matches that seem to follow him.

Ray Hansen (Big Truck) posts periodic updates on various happenings he's attending, which is the latest up-to-date news of the event.
Following Ralph Eckert around the world is something I enjoy. I live vicariously through his photographs. I have come to really admire him.
Rodney Morris posts on a regular basis and shares his thoughts on a wide variety of pool matters. On a personal note, his son is the cutest ever, looks just like him.
Scott Frost is also a regular FB poster. He really contributes a lot to the pool community through charity events, and make no mistake about it, his game continues to be strong. Scott is always upbeat and great to read.
Those are just a few that come to mind. If you're interested in reading what pros have to say, FB is a good place to go today.

Oh, I do think a few pros still read this forum, but they will *NEVER* post here again, by their own admission.
