Internet is just a way to disseminate information and I don't see any solid argument about Buddhism is made for the internet. Any religion who wants to spread can claim themselves they are made for the internet too, and this is not even restricted to religions only.
On the other hand, internet is something which will stay her and mostly will stay here for long time, therefore, Dharma practitioners should fully utilize internet fully to make the most out of it. Don't miss this chance to spread Dharma FAR and WIDE!
