As per Danny Ayers suggestions here in the comments, you will be able to navigate all your way through a reading session is Sparks! using the keyboard. In particular:
- F2 will go to the next unread blog and display all unread entries. This is the quickest and most efficient way to navigate through your blogroll.
- F3 will go to the next unread entry
Danny also suggests some sort of filtering mechanism by keywords. We actually have 95% of the code written to do this, but I'm personally torn. Would it not be better to tie into some online service such as PubSub or Technorati? If you have any thoughts, drop into our forums and start a discussion.
