I've been tempted to adopt a plugin as a way to learn how it works and see what I can add to it. Most people I have met via WordPress are great and I might even get help from some if I asked. But, there are enough who are aggressively negative that I decided not to set myself up for them. I can always work on the plugin code in secret and just use whatever it becomes myself. Glad to see people who know more adopting plugins. There have been some really great ideas which are just gathering dust bunnies in the 2 year + group.
