TLDR: Notational Velocity to vimwiki.

I was using NV, but the Find-Next feature stopped working from OSX Lion. I then renamed the file extensions to ".wiki". I used some perl scripts to remove the spaces in file names and camel-case them. Used "ls" to create an index page with links to each note. Now i can access my notes both through vim (using vimwiki) and through NV.

vimgrep and the ack plugin are good replacements for NV's search.
