First, I want to congratualte Newsblur for your reading platform. I literally tried about 6 services (web, email client, applications, etc) and only yours was a good product, and by good I mean simple, yet powerful enough to allow me to organize my reads all in one place.
Having said that, I have a problem to report to you. I’m in Mexico, so as I was organizing my feeds, I create Español and Inglés folders within categories. Well, I discovered that if there are two subfolders with the same name but under differerent parent folders, your system gets confused and treats both as the same folder. Thus, when I added a feed to my Inglés folder in Noticias, it also added it in my Inglés folder in Emprendimiento, etc. It took me a while to understand that that was the problem. At first I kept noticing that the feeds I’d added were getting replicated in different folders, even though I hadn’t done it.
I have some images I can send you if you wish.
Good luck with the project, I really love it. I expect to become a premium user in the next few days to support your product.
Regards,
Julián HR
