The way I think about it, there are two main parts to the journey here. One, there is the switch discovery part where people try different types of switches for personal enlightenment and to find those the like the best (I would including modding switches for different feels in this phase). The second is researching different implementations of those switches (i.e. buying different keyboards with the same switches looking for different feels due to materials or different layouts such as no numpad, etc.). IMO, the first phase can, one, end as there are a finite number of individual switch types, and, two, go by fairly quickly if you want it to. It's the second phase where I feel many of the (older) members are in now (although, these phases can be explored at the same time, as many people do here). Many of us have tried every (readily) available switch and are now buying different keyboards with our favorite switches to see how different manufacturers implement their design or to have one in a different layout such as the tenkeyless from Filco. For instance, I own several Alps-based keyboards and each one is a little different due to the materials used in construction. Also, now that I found a switch I really like in the Alps blacks, I want to get a "high-end" 'board in the ABS.
During this journey, seasoned travellers will help those just starting on their journey as well. I don't think the journey will ever end if the traveller doesn't want to find a place to stop and keep exploring.
