Actually, Steve Lacey of Google started this on 20% time, but it was not quite easy enough to go mainstream. You had to go to the widget building page, choose colors, copy several lines of code, create a text widget, and paste the code. It got even worse if you had multiple folders you wanted to share because you had to repeat the whole process over again. And since you are sticking them inside text widgets it gets difficult to tell which is which. Note: I had several other text widgets with code in them also.
That’s where Marcus came in. He created a seperate widget specifically for the Google Reader blogroll. All you have to do is paste a link (no code) and then you choose the colors inside the widget. So if you ever change your mind on the color it is easy to switch. The only thing lacking at that point was an easy way to share multiple folders.
I emailed Marcus last night to get his thoughts on adding multiple folders. I honestly expected to have to make the changes myself, (the unwritten rule of open source – you want a feature? write it.) but I wanted to get his thoughts on which way to do it. Four hours later he sent back a reply that he had made the change! Thanks, Marcus!
