One thing that drives me crazy about YouTube is that you can’t put a good call-to-action in your videos. Even if you use their annotation tool, it usually looks terrible.
LinkedTube allows you to easily embed a button into any video. So if you want people to visit your site or sign up for your newsletter or buy your product after they watch your video, you should use LinkedTube.
UPDATE: Don’t use LinkedTube if you’re posting a video in a blog post. It doesn’t show up in RSS readers. Ugh.
