I've been using Web2Rule for the last couple of weeks and figured I'd post a quick review here. I've got the $17 a month basic subscription.
The software itself has a few hiccups. It's not the most user-friendly thing on the planet, but it definitely gets the job done. I had to open a support ticket and received timely, open, and honest communication. I did have a problem with the developer that came up with the HTML code for implementation on non-Wordpress sites however. He seemed to take my admin info and disappear, so that was comforting...
Anyways, traffic jobs, twitter jobs, and facebook jobs are all doing fantastic. My only concern/question is that you can't increase +1 jobs to more than 1 +1 per day. I don't know if this is a glitch, or if it's set this way for a reason. All of my counters increase and I have seen a steady, albeit sometimes uneven stream of traffic. It seems like if you let a traffic job sit for days eventually it will just dwindle down and no longer execute. I've had success deleting that job and just creating a new one in its place when I've noticed that's occurring. All in all, I'd say this is a solid investment. For $17 it's of tremendous value.
