As someone with a site like that, I've found it to be very freeing to just publish some thoughts and tweak them over time. When I tried to blog, I felt too much pressure to make something super high-quality and definitive, that will stand the tests of time and never be edited... So I ended up publishing nothing besides the "I'm starting to blog again!" posts or something small and safe.

+ By tweaking over time, the work can unwittingly become bigger, better, or more polished than it'd have been if I'd tried to make something so intense from the start.
