Okay, look. I'm a big fan of freebies. Most of my sites run primarily on freebies, and I include a list of credits for each, to be fair, and to say thanks.
But being a cheapskate makes me all the more sensitive to the difference you can expect between a freebie and a paid plugin. I use some premium items because ultimately, it's cheaper for me. I can offer more; I can do it in less time; they break less often; and when they do, there's someone willing to help me out.
Now, WP to Twitter. The free version is like a beefed-up version of Jetpack's module, or any of another $5–$15 jobs out there. It offers way more ways to customize your tweets, including bells and whistles you may use.
I paid for the Pro version because it does something no other plugin does: re-posting to Twitter a certain number of times, at intervals, later in the day. I don't know how this isn't a market unto itself, but Joe appears to be one of two folks thinking this way, and the other one isn't worth linking to. I can schedule a post for the morning, and be assured it'll show up on Twitter up to 4 times that day, evenly spaced and each tweet slightly distinguished from the last. Super-awesome. The free version is worth paying for, and the paid version is worth paying more for.
But Joe's support is what's really spectacular.
- He's fast. I sent an email; he was back with me in under an hour. For two days we exchanged emails; he ran diagnostics and debugged on my server and in WP. Wow.
- He's polite. Never in all the back-and-forth did I feel disrespected or cheapened. That's hard to do in any context, but seems especially hard for techies.
- He's committed. He made no overtures of walking away till everything was working. He evenly weighted the possibility that something was wrong on my end, with WP, or with his plugin. (That he maintains a doc of known plugin conflicts confirms that.)
Again, great plugin. Even better support.
