All (bitcoin related) websites are as much worth as a buyer is willing to pay (and the seller is willing to accept). 
If you think you can make a lot of income from some website, why not buy it for more (if you have the fundings)...
It's like art:
Some see shit, which can be drawn by a monkey...others think's it's art and worth millions.
Also, with the Bitcoin community:
any site/service who started early at the beginning does have an advantage over new sites/services/concepts.
For instance this forum: it's the shittiest forum (qua look-and-feel) but has a large community no Bitcoin forum could ever surpass, because of the headstart it had.
