Hi Dave, that's great the blog is doing so well and gaining a wide audience. Lots of great photos on there. As many blog owners know, latest blog posts get added to the homepage so you have a chance of getting lots of interested eyes on your posts.
The good news is that you have a lot of control over your blog template. There are "out of the box" ready to go templates but those who want to tweak them further still, can do so with a bit of practice. You've already added web stat buttons so you have an idea of where to find the templates. For those who don't know, when you are logged in to your blog, click on "template" to choose or edit your template. For further tweaking, you may also want to look over the "template guide" which gives you shortcuts on how to add avatars etc if you template doesn't come with one. Dave, I went ahead and added yours by copying and pasting the following in your "Description" area.
You can change that text to "About Me" if you prefer. You can preview all your changes before committing to them.
<div class='avatar'><img src='<%Avatar%>' border='0'></div>
Adding another column is possible too. Just show me a pic (or website) of what you want and I'll post how to do it here. You may also want to explore giving your blog a header such as these:
Again, possible to do this by editing the template and I can show you how here if you want to explore it.
You can also post from your cellphone both pics and text if you have email on the phone and for those who like to tweet, you can add twitter badges which allows you to post even if you're away from your computer.
Also, don't forget to publish your site feed (RSS) so others can get notified when you post a new entry. In template guide, look for RSS - code will be this to add to your template:
<a href="<%SiteFeedURL%>">Site Feed</a>
