what does adding these links do?

• Digg
• del.icio.us
• StumbleUpon
• Google

thanks!

They're social networking links, allows people to add your page to the different networks

The only place you may receive interested targeted traffic from is Digg, but it's helluva hard to get.

StumbleUpon does deliver traffic - good amounts too (200 uniques-2000 uniques per day) but the people don't convert nor are they really interested in your site, though they can be.

Google bookmark and delicious are for people bookmarking sites for their own reference...paying for such service is a waste of money.

doesn't linking with other communities sort of defeat the purpose of building an community though?

why would i want to send people to another online community?

i'm still a bit confused about this...

if i activate these links, you say i will get more traffic?

thanks for your feedback and support!
