I agree, @jared.gibb is right 99% of the time, which I think by me agreeing that makes me right 100% of the time 
@GH5T I will say this, I am often in that list of top contributors, and have been for years now, so obviously, waayyyy before that little side bar thing started to appear…being in that list IS NOT WHY I provide solutions or tips via the forum on a daily basis. I actually only found out there was the ability to see statistics like that about 3 or 4 months ago.
When I first got started on Bubble in March 2018, the Bubble forum was one of a handful of places to learn about Bubble. At the time there was maybe one youtube channel devoted to Bubble that provided some good videos for basic, beginner level stuff, but the hard stuff was advised via the forum, or from a small set of so called ‘experts’ offering their training services.
I was hitting a brick wall on a must have feature of my first app, and so I spent what for me at the time was a lot of money on training sessions, and, after 2 training sessions at $2/minute, the ‘expert’ stated that he didn’t think Bubble was able to do what I was in the training session for, which was a basic search and filter using an Advanced filter. At that time, Bubble was fully capable of performing that task.
I turned to the Bubble forum for help, because, quite honestly, the experience with the ‘expert’ and the brick wall I was hitting, was pushing very, very close to giving up on Bubble. Luckily, on the forum, one of the real OG Top Contributor, took the time to provide me the step by step instructions necessary to get it to work.
I’ve been paying it forward ever since, and will continue to do so, with or without the Top Contributor side-bar.
In my time providing tips and solutions on the forum, I also have had the chances to learn SO MUCH from others who have stepped into a thread and provided a better answer than mine, or provided guidance to me that I was wrong and the correct approach is what they laid out. I continue to learn something new everyday on the forum.
The majority of that is driven by those that find the forum as the main tool for promoting themselves and their services. I honestly do not feel that it is driven by a desire to be highlighted on a sidebar to the fourm that I believe most people scroll right past without even noticing it.
