I know this isn't the place for this but consider showing the comments that are behind "show more comments" on the same page as the rest.

Currently if I click on show more comments, I seem to be redirected to a new page with only that comment tree showing. It shouldn't work that way. Please look at reddit how they are doing it for an example.

Another tip, notifications; I can't tell if there is a new post on my feed or a comment for me - there is no difference in the UI for an user. This is bad design, again. When implementing these normal social media functions, I'd suggest to look on other popular sites and how they do things and try to replicate.

Thank you for your time.
