I passed by the old building today that used to be the location of the tech store CompUSA.
That was where you could buy things like Netscape Navigator Gold in a box (CD).
Thinking back to when Geocities upped the storage quota to 3 MB. You could avoid using the storage by linking the image library they had.
Also fun: Tripod and NetTaxi.
Best (for me) net chat for awhile: WBS – Webchat Broadcasting System. I still have friendships that originated there.
Favorite blogging community 2003 onward: MyOpera Community. Until Opera browser got sold.
