I think it worth doing anyway (even to show to Geeks for their opinion about your work - what you doing wrong, what's good). Some of my clients asked me for price list to show to their friends and instead of it I gave them my website address (easiest way to see prises, service, contact details, little bit about me, examples of my work). I had quite a few clients that find me through my website...
I definately find my web site useful. I have all my info on there. Some reasons i find it helpful are:
1. If clients loose my business card, they can get my phone number.
2. If clients have to choose some nail art, they can look at the gallery before deciding.
3. It adds a subconsious credibility to your name..."wow, she has a web site!!"
4. also you can have commonly asked questions onthere and a caring for your nails page, which i am going to do soon.
thats all for now
PS. sorry about the spelling, i have had a few to many wines, i think!!??!!
