Plain, simple, and surprisingly hasn't been done yet:

I have been using the Internet for...

• 0-3 years
• 4-10 years
• 11-15 years
• 16-20 years
• 21-30 years
• I had one of the first hundred nodes on ARPAnet.
• CowboyNeal
• I don't use the Internet

I chose the cut off years for the first two options based on the type of web that existed in each period. If you have been on for more than 3 years, you know what I'm talking about.

Surprisingly, CowboyNeal makes sense in this poll.

I was almost tempted to add a 'Net option, but realized that it would invalidate my desire to not see a certain /. author.

ALL HAIL BRAK!!!
