I love SU, it's amazing how much stuff you can find there, I only started this week, 120favs already, of course including my own website but it's cool to see a lot of great logo design, great tips on any form of design. Best of all, it's a bookmark tool that shows me things I'm interested in, although sometimes it's the same page popping up but I don't really mind it. I have the stumple tool bar and have been playing it for a few days now!
You need to keep stumbing new content from all kinds of site. If you only focus on submitting post from your own webpages, you won't get increasing traffic. You should visit other's sites sometimes and stumb their content as well. It will be helpful to attract followers on stumbupon.
I am very very new to stumble upon.... can some body give me a link to learn the interface of stumble upon. and I want to know what is stumbling and how to get more followers... plz.
