Khürt, Thanks for downloading Yarns!

I have not been testing with large numbers of RSS feeds, so I don’t have a solid answer. Yarns uses a simple cron job to check ALL of your subscriptions every 60 minutes. With a large number of subscriptions, this would involve a large number of requests each hour. I plan to improve this but it will take a little while to figure out the best approach.

I also haven’t tested using markdown. I’ll give it a try and let you know
