Octopress自身不支持评论功能，不过我们可以使用第三方的评论系统，国外的有Disqus。下面介绍怎样在Octopress中使用Disqus。
首先需要在Disqus注册一个账号，登录后点击Add Disqus to your site，然后添加站点信息site name和url，记下右侧的name
然后在_config.yml文件中进行下面设置
# encoding: UTF-8
module Jekyll
class CategoryListTag < Liquid::Tag
def render(context)
html = ""
categories = context.registers[:site].categories.keys
categories.sort.each do |category|
posts_in_category = context.registers[:site].categories[category].size
category_dir = context.registers[:site].config['category_dir']
html << "<li class='category'><a href='/#{category_dir}/#{category.to_url}/'>#{category} (#{posts_in_category})</a></li>\n"
end
html
end
end
end
Liquid::Template.register_tag('category_list', Jekyll::CategoryListTag)

如果会出现:
添加超过一个tags之后，rake generate就会开始报错了： Error :Liquid Exception: comparison of Array with Array failed in page
只需要将1个tag重复2次以上使用就可以解决。
1.第1个post加的tag是：tag1，第2个post加的tag是：tag1
2.rake generate
3.第2个post的tag随便改：tagXXX
