I write a few blogs (non beer but brewing is mentioned - a lot of drunken landscaping) and the one thing MOST blogs are are boring - the reason is that they are all facts. A good blog will have your personal thoughts, discoveries, ideas, conquests and disappointments.
This is the way you get readers because people will live their lives through you. By showing that you are not a robot people feel that what THEY do, their conquests and disappointments are not abnormal but normal.
I have had my main blog for 3 years with 528,000 hits! People love train wreaks (like when my buddy and I felt a wheel barrow was too heavy so we each took one side . . . lasted almost 1/4 second - no injuries). After that incident I had a lot of comments from other people that had made fools of themselves.
Or when I was brewing two pots of wort on the stove at once (for a full boil) and they both boiled over at the same time!! (There is some timing involved with boiling two at once).
Make it you personal discovery.
