I'm in the middle of taking the "Power Searching with Google" class (http://www.powersearchingwithgoogle.com/class?class=1&lesson=5
) and I found it amusing that the host couldn't admit that hashtags were made popular by Twitter, to be followed shortly later by an emphasize on how to search Google+ space. This is even more amusing because in an earlier video with the Google Engineer, +Matt Cutts
, he claims that Google takes its objectivity seriously. Word to the wise: it's examples like this that undercut your objectivity.
Otherwise, I'm finding the class interesting, and just the right amount of video to activity balance, with a good balance of covering the basics to moving towards advanced knowledge. Looking forward to continuing it.
