I would start out with a high interval then slowly decrease for each individual user based on the number of times they post on each service.

You wouldn't want to go to my twitter page 20 times an hour when I only post once in a month. It might make more sense to check every 30mins to 1hr.

Thanks for your response. The issue isn't so much for how often they post, it's more for how often they receive communiques. Being a small-timer, I'm trying to figure out the most resourceful way of accomplishing this.
