According to comScore, YouTube is the second largest search engine next to Google. It however, does not have a solid monetization model. Dave says YouTube users don’t care what’s going on around them. They simply want to watch a video. YouTube users turn advertisements away much like they do on television, by either flipping to another channel or leaving the room until their program comes back on.

Twitter is a whole different story altogether. Look at all the applications it provides such as TweetBerry, TweetDeck, and our very own Twellow. Dave then raises the following question: what if Twitter would start charging for their usage? How would that change your business strategies on Twitter?

Twitter recently announced that Pro accounts are coming this year but has yet to disclose what they consist of.

Moving right along to Facebook. As discussed in our interview with Tim Kendall, contextual advertising on Facebook is based on the freely submitted data Facebook users provide. On the contrary, Google and the other search engines base their advertising on the searcher’s past history.

Facebook’s model is much more accurate than the search engine’s technique. Most users conduct many searches at work, which does not reflect their actual behavior. Facebook uses the information users readily give to them as part of their preferences.

On a final note, Dave points out that Google needs to incorporate a “business account” for Google accounts since sometimes many people are logged into one person’s account. He suggests giving the account holder the ability to choose who can have access to what.

The first topic I asked Dave about was Facebook Connect. He blogged about the topic and brought up the privacy issues it raises. The service enables Facebook users to “connect” their account with other sites in their network. Users have access to their friend’s activities on those sites as well. Dave points out that while this service attracts online advertisers, it still raises many spam and privacy concerns.

“There’s no such thing as privacy on the Net anymore.”

Topic #2 involved Google and their search results editing tool, SearchWiki. To experiment with the new editing tool, Dave set up an account and changed his name to Matt Cutts. Using that particular nickname, he went into Google’s results and gave his own website an impressive review. This action proves that SearchWiki does not have clear limitations or guidelines.

From a reputation management standpoint, this tool could be deadly. It is easy to set up an account and if competitors utilize the tool, the results could be very unfortunate for some companies. Google has not yet created a means for discerning the good comments from the bad.

When asked if he thought Google would soon amend the tool, Dave responded with:

“They’re Google – they do whatever they want.”

Topic #3 and the last main topic, revolved around Dave’s expectations for 2009. Sharing the same opinion as many others, Dave expresses his belief of seeing much more with Google in personalization and its impact on search results. Dave describes a wish of his that Google would roll out a link posting tool that would eliminate backlinks. Other expectations include more integration and date stamping on blogs.
