First thing I notice about the new youtube layout is that my videos are popping up more around youtube. All the hundreds of hours I've spent on SEO optimization is paying off.
Second thing I notice about the new youtube layout is less new subscribers. Subscribe annotations don't work like they used to. They don't send you to a page with a sub button on it anymore.
They've moved the sub button to a discreet location that doesn't stand out like it used to...
Since I'm getting more views from the search engine and youtube's suggested videos I'm adding more annotations that link to other videos and making them more attractive looking
