I’ll pay to host my own content - but if it’s just static content - that’s essentially zero.
Also, I’ll make tools to make it easy for anyone to create their own self-hosted website.
No ads needed.
And if I make a product or service of value, I’ll sell it - without ads.
Word of mouth recommendations are great. Somebody can make a review or a blog post about it because they like it.
Others can find it when they search for it - because they need it.
Think about it - how many things/services do you buy because you saw an ad versus because you had a need and sought out the best product that could fulfill it.
In fact, I think it would be awesome if a new search engine could step up - ad free web search (excludes any website that uses ads).
