Would you perhaps share how you did it with an example? I really like the concept of Huginn, but haven't had the inclination to play with it further myself; setting something up for my own sources' summaries would be a good way to start, I guess.
1. A website agent that parses the Reddit JSON api (just add .json to a subreddit URL)
2. A trigger agent to filter based on your criteria (ex. minimum 50 points) and transform the JSON to a nicer message
3. An email digest agent to bundle the messages into a single email
Each one of these feed into the next so you go from the raw JSON to a nice email. Then you can easily just feed more things into the email digest agent to add more to it.
Let me know if you have any other questions, my email's in my profile. It was pretty confusing for me to get started but I'm getting the hang of it now.
Now that rss feeds I like and newsletters I like are in wordpress as a post.. I have a plug in that sends an email digest of what's posted...
What I like about my ghetto setup is that I can easily search and get "related" articles..
