I came across Beyond 3D through Googling about some GPU. I cannot really remember which, but it was certainly after nv30's failure. I was interested in GPUs since the GeForce 3 (my first modern GPU was a GeForce Ti4200 128Mb) but I did not have regular internet access until 2002. I joined Beyond 3D much later after frequenting the forums as just a reader. Even as a reader I learned a lot about how GPUs work on a high level from all the discussions (all the different units that make a GPU, the pipeline, etc...). I decided to join after Fermi was "revealed" by brightsideofnews website as a cross between a CPU and a GPU (which was bullshit of course, but to my "ignorant" mind it sounded exciting). Also the fact that Fermi really brought about non-graphics uses for GPUs on a grand scale (even if G80 and GT200 were already capable, Fermi brought C++, Fortran etc, support out of the box) was impressive.
In the end my "theory" about GF100 (that you can find on the thread about our first posts) sounded good enough for me to post about it. I guess that just like everyone here, I enjoy speculating about upcoming GPUs and that was the main reason I joined. It is also the only hardware forum I still maintain a regular presence because Beyond 3D has, without a doubt, the most knowledgeable people from all the tech forums I know. Its nice to speculate, but without someone to keep us "close to the ground"/realistic it is a fruitless and sterile exercise.
