Although this book was written over 10 years ago, there are still some practical ideas in here about how to increase loyalty and to keep people coming back to your website. However, the author definitely underestimated the reach and relevance of broader social networks such as Facebook, which has since turned into a company that connects pretty much everyone and continues to purchase smaller social networks.
One revenue channel the author mentions is the “tip jar”. Are there any websites that actually use this method for generating revenue and encouraging users to send money to other users as a means of a “thank you”? With the internet being such a widespread resource for people to review, rate and recommend (author’s prediction of that was spot on), anyone and everyone is able to post their opinions on multiple sites for free and for other people to view for free. Keeping that in mind, I think that some of the ideas in this book are outdated as users these days are not likely to send strangers money or website credit (although a reward for recruiting more members to join is still valid ex 3 months of free subscription) when there are so many other resources and reviews to compare that do not cost money to participate in.
The theory/prediction that social networks will drive product and service sales is certainly true to this day as can be seen with the influx of influencers and digital marketing.
All in all, there is still some value in this book but it would be interesting to see a newer version and how it applies to the way that people interact and connect on the web today and how even smaller scale influencers can make money based on marketing themselves on social media versus an entrepreneur creating an actual website and trying to create awareness for their site in an time where there are endless possible sites to join and differentiation is a challenge.
