Thought I would briefly weigh in...
The miles and points blogging world is so different than it was when I started five years ago and even so different than roughly two years ago. The various ways to monetize your site beyond a hobby blog are also so different than they were. It is still a very evolving and maturing medium.
The volume of traffic required to do business with various entities today is different than it was at any point in the past, and likely it will be even more different going forward. I'm sure the type of traffic you have will be even more relevant in the future as data and metrics are even easier to capture and measure.
In terms of content on my site, it was always first and foremost about things everyday families can do to travel more for less. It always was, and it presumably always will be. Mainly, that's just where my interests happen to be. A handful of fancy miles and points redemptions taken while we had a pretty self-sufficient four year old at home (and grandparents nearby) knowing we were planning to very soon head back into the infant years didn't change that. In fact, I strongly encourage families to take those sort of trips when you have the chance between little kids since the infant years are really not the time to do it!
I can see how to those who didn't know our long term plan it looked at the time like a shift, but it was never a shift, it was a planned blip. Either way, I can assure you that writing about fancy redemptions increases, not decreases, traffic, but that was never going to make-up the majority of my content since it does not make up the majority of my travels.
I'm lucky to have been able to pay the bills writing about stuff that I love for over four years, and I hope to be so lucky as to find a way to keep doing it for many more. Only time will tell. For those of you who do read the site, even if only on occasion, thank you.
