I enjoy wandering around personal websites.
Here is a list of some interesting ones:
- Cosma Shalizi’s bactra.org — its depth and breadth is astonishing
- Paul Graham — has written so many great essays
- Bartosz Ciechanowski — has some great interactive content
- Brian Lovin — check out the AMA and Bookmarks. The website itself is open source
- Andy Matuschak — his public notes are an interesting open experiment
