Here's my response to your advice, point by point:

"1. Decide what your blog is about and stick with it."

Maybe, but I found myself spread pretty thin as I tried to keep up with more than one blog. After a brief hiatus recently I decided to do all my blogging on the blog I've had since January 2006, Igneous Quill. I blog mostly about theology, but also about a little telecommunications tech and some personal stuff. I post in English and in Portuguese.

"2. But don’t stick with it too much."

Agreed

"3. Index your posts"

I make a list of "Recommended Posts" and edit it as I go along. I've noticed, though, that quite a bit of my blog's traffic comes from Google searches, so the indexing really doesn't do much for most incoming traffic.

"4. Include your email address"

It's on my blogger profile.

"5. Use pictures"

Sometimes. Too many pics gets distracting, and though blogger has a pretty generous limit on photo uploads, I'd just as soon not hit it too soon.

"6. Don’t be too longwinded"

This varies, but I tend to agree. In depth studies take as long as they take, but in a blog format it's better to take them apart into several smaller posts. If there's a document for the study, it could be uploaded to an online storage site and linked into the blog for downloading.

"7. Don’t moderate comments"

Nope. I've seen too many disrespecful "discussions" and nasty comments from anonymous readers across multiple forums online over the roughly decade and a half I've been online to allow unmoderated comments on my blog. I've had to reject several very mean-spirited anonymous comments to my blog over the two years I've been doing this.

Besides, it's MY blog. If they want to say whatever they want to say, they can set up their OWN blog.

"8. Participate in the discussion"

Agreed

"9. Don’t post too often"

Ha! I've been keeping myself to one post a day, two MAX for a while now, but recently I said "To heck with it" and have been posting everything I want. I know, people won't be able to keep up. But again, the people who are looking for the things I discuss will catch it on Google.

"10. Don’t wait too long between posts"

Agreed. A blog that hasn't been updated in two weeks, with no sign of where the blogger went, is as bad as a website that hasn't been updated since 2006. Dead in the water.

And I can spell URL. (I’m not sure how to pronounce it, though.)
