its a big cycle, the service will sell everyone cashes out, some other team picks up where the last service left off.

Delicious -> pinboard anyone ?

I think theres a pattern of products deteriorating after purchase for one reason or another, either not enough attention or founders leave or consumers find another product from a hot startup thats in the same space. While having a paid option should be encouraged, no service yet is something that I can't absolutely live without where theres a free alternative, and if theres something worth paying for, someone will build a free service.

I'd rather encourage users to turn off ad block on sites they like, and click on links that are relevant.
