FWIW, I went to stackshare today and was interested in the stackups feature. For the first time ever, I decided to click that I used something (bootstrap), then I ended up registering through github and submitting my site.

However, once I was logged in, I could not find a way to get back to stackups. The top/left home icon takes me to trending tools and stacks. Posts seems to be stacks of major companies. Tools and services doesn't have stackups.

I searched for searched for "Stackups" in your search bar, and the top result was "Stackups". I clicked more. It lists 50 results, but then no actual results were listed.

I was only able to get back to the stackups by logging out, and returning to the home page. Maybe I am missing something obvious, but just FYI that was my experience.
