Try Tumblr, it's free, and so many people use it! Bsically, you'd put pictures up of your nails, try out new trends, put tutorials how to do that stuff up. And why shouldn't you go for it? Have fun, and go ahead and do it if you want to!

Yeah..actually picture of a higher quality would make a difference... prepare numerous nail art designs and take a shot of these...when you have 20 nail art designs you can start building up a blog...you can also make product reviews to make the blog more versatile..you'll find free blog templates from blogspot and other companies.....:)

I agree with Iris....photos make ALL the difference...however you can start the blog with reviews too or graphic tutorials you know.. when you draw how to make different nail designs...you have tons of options to make your own nail art blog....:)

Most people have already said the important parts. Hi quality photos, tutorials, stay up to date on new trends and designs, read nail magazines like nail up, tumblr will give you easy access to an audience. Just be creative and learn all you can. You have to conduct yourself like a pro if this blog is a nail blog catering to an audience rather than a personal blog catering to yourself. I run a fashion blog on tumblr called gyaru-coordinates and i cater to my audience so i keep them up to dateon trendsin that style and show them how to coordinate outfits all while keeping myself in the know by reading as many magazines as i can. This is basically what you needto do but for nails.

Sorry adding an example of magazine tutorial nails here
