Another considerate addition for your readers is bookmarking buttons, placed high up on your blog. I prefer the Add This button, as it's clean and efficient and doesn't clutter up the page with endless bookmarks.
You might not understand the mechanics if you're new to blogging, but trust me, your readers will and they'll appreciate you for it. It makes your blog very visitor-friendly.
If you have a Blogger blog like this one, be sure to add the Follow Me gadget so others can see who reads your blog. All these add-ons are demonstrated in the right column.
