We’re very lucky to be living at a time when some web sites are still charging. It used to be that that was the primary income model – but with the costs of internet construction plummeting, and the availability of income-producing advertising increasing, it’s seemingly less necessary to charge, at least for basic features.

That means, to me, that there are areas of the net that can easily be conquered by free sites that accomplish the same thing. Take online dating for example. I’ve tried Yahoo personals and eHarmony. Both work reasonably well but are also reasonably expensive. Are there any free-as-in-beer dating sites out there? Not any that do a reasonable job. Now all it takes is for me to build a good dating site that’s free, and people will like it. What other areas of the web haven’t yet caught on to the trend?
