There are a ton of tools for getting things done and improving our blogs. If you have a tool you like to use and you think others will enjoy, post it here to help others.
To kick things off, here is a tool I came across today:
Free Website Performance Tool and Web Page Speed Analysis
If you put your blog address into the form you can get a report of how fast your blog would load for given connection speeds.
I don't take it as 100% accurate, but it will give you a good reference for how long it takes your blog to load on slower connections.
It is also a good look at how many things are loading in the background before your blog finally displays.
It can help you understand which widgets and things might be dragging down your blog and potentially losing you blog readers.
