known issue:

1. OneFeed is not perfect parsing all the feeds there using XMLHttpRequest.
   For example: element with namespace (due to the lack of getElementsByTagNameNS function), not escaped content, etc.

2. OneFeed relies on XMLHttpRequest.
   Using invalid feed (for example: big XML file like http://www.w3.org/TR/1998/REC-xml-19980210.xml) will freeze / crash Sidebar.
