The front page is too empty. You must add some links to popular topics (quadratic equation? topology?) and some link to random topics. Something like the Wikipedia main page.
Can I edit without an account? Please. I'm too lazy to create one :) . I guess it's a tradeoff between spam and making it easy to make small contributions.
Thanks for the feedback. Yes, it seems I need to redesign the site to make it easier to navigate and feel less empty. I like your suggestions about adding popular topics.
Thanks for letting me know about the error. Right now Mathpendium has around 1000 entries, and so it is easy for some errors to slip through the cracks.
I was debating about whether or not to require an account to make a contribution. As you mentioned, making an account helps decrease the chance of spam. However, I am open to allowing anonymous contributions, and it is good to know that others would appreciate that.
There is an error in https://mathpendium.org/view/5e33c092981ec41bc6b27939 (two missed $ and the rendered is unhappy with \subset)
