Few days ago I finished making my first Yahoo! Pipe, which collects info from YouTube channel feed page, and republishes that info. Yesterday I noticed, that Yahoo! Pipes badge output does not support Opera – with Opera, nothing is shown. It is strange that Yahoo does not fix this, maybe it is because Pipes is a free product. About 3 % of my blogs readers use Opera.
You can leave out the first line, if your template already loads jQuery. Make necessary configuration changes (change YouTube user name, for example). I did only very basic CSS, you can of course modify it to your liking. Code can be used also outside Blogger (in any html page).
