The list of web 2.0 tools available today is astounding. I could list more, but these five are really the top tools that I use every day (and actually, I'm stretching it to add GrandCentral to the list, but I just like it).

LinkedIn:
I think I am on LinkedIn 24x7. Seriously, I log in at the crack of dawn and never log out. Today, it's the best tool I have for connecting with the people that I want to meet - need to meet - have to meet! You can find my profile HERE.

Twitter
I'm not on Twitter 24x7, but I'm diggin' the fact that I can keep up with real-time activities of the people I want to follow. Here's a recruiter who knows how to use Twitter effectively (Geoff Peterson).

Facebook: (my profile)
Facebook is just cool. The new apps that are added almost daily just blow me away. I use Facebook to connect with people in the wireless business, but I also use it because I'm intrigued by the constant changes and the evolution of how people connect. You can almost watch it happen real-time on Facebook.

GrandCentral:
It just makes sense to have one phone number that rings all your phones. 972.200.3531.

Jott:
I blogged about this one the other day and I'm having fun with it. Good solution for people who try to text while driving (or even people who use their video while driving....just kidding). Give it up - get your Jott on.

So, who's in your five?
