Things that I would be really interested in seeing would be a Recipe section with two sub categories, All Grain and Extract.
Then a category for all the newbies like me possibly called "Did I Ruin It?". A place where all of us newbies can ask about the different things that we did that may or may not have ruined our first batches.
I also would have loved to see a category on yeast strains. Where people can talk about which are their favorite strains and favorite temps to ferment with them in different beers.
When I was first looking for a starter brewing kit I would have liked to have read what others recommend, so that might be a good category too.
Just some thoughts.
Maybe even a category about growing hops. The local home brew shop was selling rhizomes when I went yesterday and I was thinking about giving it a shot.
