Woah woah woah. You read my dotfiles?
Yup. Helped me a lot. While not directly related, they allowed me to actually configure my Emacs to have some of the features for Haskell that I was sorely lacking. Since I don't like Sublime or Vim (although their selection of Haskell-related plugins actually works out of the box :/) and Leksah can't be even installed without some serious work on Cabal I had to default to Emacs.
Configuring it for Idris was easy-peasy afterwards.
Most of the blogs I've read have been focused in on one or two things.
On the other hand, many of them are intended to be about one or two things but quickly devolve into a lie-spiral of "I know that this is an unusual topic but…" that after a while happens in every third post. Either have two or more blogs and keep them separate or just cut out the middleman and make a topic salad from the very beginning. ;)
Anyway, I do encourage you to write about whatever catches your fancy.
