A wiki isn't the ideal format for all types of content. You can't do calculations in a wiki, for example. My Toolbox originally arose to fill that content gap.
...But then it turned out that 6 months after launch, the English wiki was still barren. I think Aidoru was the only one actually adding content. I sounded out the community to see if everyone was interested in pitching in to write guides and such, but in the end, I didn't see any real interest. So I just did it myself. And since I did it myself, it seemed appropriate to stamp my name on it and call it my own.
Since then, a few people each have focused one one particular task and made a tool to accomplish it. I reach out to these community leaders and try to incorporate the better tools into my Toolbox or link to them in my guide. But some of these users don't even publish their tools; they just share them with their Union and friends on Discord. Others start projects and don't finish or maintain them.
In any case, the current ecosystem evolved to replace the 'nothing' that we had for over 6 months. It's not like the community made a conscious decision to fragment. This was the remedy for collective apathy.
