Bitcoin is definitely the next generation of internet currency. It has already become big and growing at an exponential rate! However, the blockchain is still at a very nascent stage to call it a next web, even though bitcoin is one of the use cases of blockchain!

Research and development is ongoing by the smaller niche companies as mentioned in the article under fat tail analysis! Who knows, we will probably see another social media to replace Facebook or another eCom website to replace Amazon in future! But it's now little too early to call blockchain as the next web! Potential is obviously there but needs to be explored even further!
