I love the witness functionality, I used to use Steemwatch but Ginabot is much faster and @neander-squirrel is very responsive. There are some new functions that are really cool that are coming out, but not sure I can spill the beans so I won't.
@neander-squirrel doesn't charge a cent for this either, which is crazy. If you can throw him any tips, I'm sure he would be very grateful.
