(defn read-tweets []
  ;; this opens a file
  (with-open [rdr (reader "data/tweets.log")]
    ;; this returns a lazy-seq, which is bad since file is opened first?
    ;; results in IOException Stream closed
    (for [line (line-seq rdr)]
      (let [[apikey timestamp entry] (split line #"\|" 3)]
        (vec [apikey timestamp (json/read-str entry)])))))
