One more thing, the articles are from all around the net.
I wrote it as a tool for myself to handle the infinite content in my RSS, when I leave my RSS for 24~48 hours, I can't handle the backlog while it's too much, not mentioned after a weekend... so I tried to optimise my time and looking for just the top content. I share the tool with friends, and they was very excited and more and more people ask for it, so I decided to take it out so anyone can enjoy from it.
Hope it will help you too, and I will be more then happy to get any feedback to make it more usable :D
Thanks for trying it!
The tags are from the source as the publisher defined it,
basically you are correct that those are kindly the same, but programming most of the time more low level, while development are more global. You can select multiple by subscribe to the weekly email :D.
RSS I believe will come in the near future.
Thanks again for the feedback!
