If you look at the bottom of my left sidebar, you'll see a number of statcounters and clock that I'm trying out. I'll delete the ones I no longer want later. With the exception of Clustrmaps, you just click on the statcounter you want, and it will take you to the page showing how to get the code. They are all free. You can get Clustrmaps from here. Probably the most informative is Statcounter.
Once you've copied your code, go to your blog and click on "You" at the top left hand side. Then click on "Change your design" on the top RHS. Scroll down and click on "Customize your sidebars". Tick the box, "Embed", and then "configure". Paste your code in the "Widget code" box, click OK, then click on "Apply". Your counter should appear in your side bar when you return to your blog. If it doesn't all appear, you may need to alter the code at the top to <div style="height: 1200px;"> by changing the existing number. If you wish to add another counter, choose your counter, and repeat the above until you come to pasting your code. Make sure that you paste your code between the existing code but above the </div> code at the bottom.

I guess I shouldn't be surprised that blogging ware can do this, but I feel like I'm being watched now.
Happy to help with anything you need to know. I suggest you first get some neighbours so that you can read their posts when you click on "Your Neighbourhood". Easy to add them when you click on all those emails you got when Voxers made you a Neighbour.
Click on "Reply" when you respond to a comment. That way you get a notification of the comment. That'll do for now.
I'd better clarify the above.
