I have just read an article that claims that the day of RSS are numbered, and that the role it occupied until now will be completely usurped by Twitter. That stance certainly holds water, but if you are an ardent RSS enthusiast who wants to hold onto such format, then this site is nothing short of a must.
Essentially, it will empower you to take several RSS feeds and combine them together. In practice, this means that you will dispense with subscribing to feeds one by one, and (more importantly) you will be able to share your favorite RSS feeds with others in a more or less instant way.
If you want to give Jumbra a try, you can do so without having to register or disclose information of any kind, and combine up to three different RSS or atom feeds at once. If you want to meld more together you will need to sign in. If you have a Gmail or Google account, then you are ready to start rolling on the spot.
