I'm actually only familiar with the arXiv, for physics and computer science research. I don't know much about biorxiv or Zenodo, but they both seem much better than a personal website or github page.

The arXiv has overlay sites, such as http://www.arxiv-sanity.com/ or https://scirate.com/ , that improve discoverability over the basic arXiv interface; for example, you can browse all the papers in a given area posted in the last two months, sorted by some proxy for "interest." Of course there is also Google Scholar, and perhaps there are better ways.
