For professional connections I prefer to connect on LinkedIn, when you send a connection invitation by all means explain a bit more than the standard message on why you would like to link up with me.
Please do refrain from sales pitches before you get to know me and whether I am even remotely in your target market, because such efforts result in instant disconnections for me. http://www.linkedin.com/in/ancoppens
You can also just like my facebook page and keep up-to-date with my posts, my personal profile is reserved for friends only. 🙂 http://www.facebook.com/pages/An-Coppens
I equally post on twitter under my own name: @AnCoppens
If you would like to use conventional methods of contact me, please use my e-mail couldn’t be easier: email@example.com or book a meeting
