That's a good start. It starts small, but it can go fast. For now, it is often quite important that people make new posts. I see that a lot of people are very comfortable to comment, but smaller communities hardly get any new posts.
But then once you start helping with that, before you know, you write a whole blogpost.
Be careful, it's addictive. It starts with a simple "This is my first post" and soon enough you notice you are posting a 20k word essay on !onebag@wayfarershaven.eu why you think 40 litre bag is the most optimal on a 5 day trip.
Exactly, the thread would go on and on and someone would come in with calculations as to why you should instead have 15 litre bags if you have two bags.
In all seriousness I believe at some point it will be quite similar here :) give it time, the enthusiasts will figure out how to join and voice their opinion!
