This question requires speculation.
We hope that Hubpages will be faring very well in two years time.
However, the answer to this question depends on who you ask.
People on this site have very different opinions on this matter, as you can see in the forums!
The answer partially depends on every person's account in hub pages.
Will people continue to write quality hubs or not?
It also depends on staff and management, and it also depends on changes with Google and also the laws about banning sites.
