Marginally better version of https://github.com/JamesChevalier/hashtagged/blob/master/app.rb#L17-L27

gistfile1.rb

timeline     = client.user_timeline(@user_name, { count: 200, include_entities: true })
hashtag_list = timeline.map { |tweet| tweet.hashtags.collect(&:text) }

@hashtags = hashtag_list.uniq.map do |tag|
  { text: tag,
    weight: hashtag_list.grep(tag).size,
    link: { href: "https://twitter.com/search?q=%23#{tag}", target: '_blank', title: "#{tag}" } }
end
@hashtags = @hashtags.to_json

Oh and https://github.com/JamesChevalier/hashtagged/blob/master/app.rb#L18 should be

hashtag_list = timeline.flat_map { |tweet| tweet.hashtags.map(&:text) } instead of
hashtag_list = timeline.map { |tweet| tweet.hashtags.map(&:text) }.flatten
