I primarily use twitter to interact with other like minded people; most of the people I follow are active in the website design / development communities, and share related articles which I often find inspirational. I also post information relating to web design & development as well as jquery and php.

Joel Vardys Avatar, I use all over the web to distinguish myself

I display my designs and finished work on Deviantart this allows me to get opinions and ideas from other people in the online community. I also spend time viewing the other Devianations where I leave comments and help them with aspects I think could be improved.
Please have a look at some of my work.

LinkedIn is a website which I use solely in a professional manner, I connect with people I have worked with or people I plan to work with in the future. I have also joined various groups which relate to web design and development. Feel free to add me to your LinkedIn network.
