The long-awaited Google IPO finally took place today, with the shares closing at $100.34 on its first day of trading on the NASDAQ. Now that this event has taken place, perhaps we can hope to see the Google employees getting back to the business at hand. An update of the public display of PageRank on the toolbar would be a nice start. Despite the fact that the PR display is relatively meaningless for SERPs results, it is still an important tool for search engine optimizers when requesting backlinks. So come on Google, the fun is over. Time to get back to work!
