Use a consistent name when leaving comments on blogs. Consider appending a tagline, perhaps your blogname or other personal brand name.
When I leave comments, I'm now "Ted Demopoulos, The Blogging for Business Guy."
Before I was just "Ted Demopoulos" or sometimes "Ted Demop" or even "teddemop." Long ago I decided I needed a consistent name when leaving blog comments, so I started exclusively using "Ted Demopoulos" even though it's looooong.
A few months ago I noticed others adding "tag lines" to the name they used for leaving blog comments, and decided to append my blog name, making me "Ted Demopoulos, Blogging for Business." I like this much better than just my name!
Friends sometimes introduce me as "The Blogging for Business Guy" -- hey, I did co-author the Blogging for Business book. My blog comment name is now "Ted Demopoulos, The Blogging for Business Guy."
So, if your name is Joe Smith or even Zaphod Beeblebrox, consider using a consistent name with a tagline when you leave comments on blogs.
