What makes a blog successful - Part 2

I successfully added topic archiving to my blog, though I haven't finished tagging all my old posts yet. I have also rearranged my sidebar, which was a bit messy after migrating to New Blogger.
Let's see the last 10 of the Twenty Usability Tips for Your Blog and how they can help me improve my own blog.

11. Include a list of related posts beneath each post: the author of the articles refers to a Wordpress feature that allows you to list all related posts by simply typing keywords in a widget field. Blogger doesn't seem to allow this, but I've found a discussion on Blogger Help that could shed some light on how you can do it manually.
12. Allow users to contact you offline: I'm not very keen on displaying my e-mail address openly online. Readers can contact me via comments or Odeo voice messages. Maybe I should see if there's some kind of widget that allows them to send text messages to my inbox without revealing my e-mail address.
13. Present your real viewpoint: this is what blogging is all about in the end, isn't it? Express opinions and be ready to receive comments backing you up or disapproving of your ideas. The art of comment writing is to do so with respect and and open mind.
14. Write for your future employer: Good advice for young people, who tend to be too emotional and unrestrained when writing. Something that we teachers should include in Lesson 1 when teaching our students to blog.
15. Include a Top Posts section: well, well, I don't think I've written anything to be top of a list (YET). No use creating an empty section :-(
16. Provide an index: Even when my aim isn't to increase traffic on my blog (I'm happy writing for myself although this is not a very "blogish" concept, it'd be good to have a table of contents to see what I have on my blog. I'll have to search for a site map index plugin like the one Tom Johnson mentions in his post.
17. Get your own URL and match it to your blog’s title: I did this as far as possible when opening my blog, though I had to use a dash instead of a dot before the "ar" in the URL.
18. Include a Recent Posts section in your sidebar: I've found a Help page on Blogger that explains how to do this. Anyway, the date archive can be easily expanded to show recent posts.
19. Reward commenters for commenting: the idea is to have a list of the most frequent commenters to help build a like-minded community of readers. There's a Wordpress plugin that creates such a list automatically. Nothing like this in Blogger. But I like MyBlogLog list of recent readers.
20. Post often: This is perhaps the most difficult goal to meet for me. But it's a question of creating the habit, like going to the gym (I've been away from it for years!). I guess I'll have to go on reading about blogging and related stuff in order to find rich material for my blog. Now that the manual revision is over, I will have more time available for learning and sharing.
