I just want to see what be what 1" sensor camera is capable of for Internet use-where else could I ask? Maybe it could be a whole new forum, "P&S Cameras".
It depends how old the design is. If it's less than a decade old, then more than good enough for internet use. Look at the number of pictures posted online from 6mmx4mm phone cameras.
The issue with most digital P&S cameras is lens quality - or rather lack of it. They're usually pretty sharp, but have hideous distortion and poor flare resistance.
The exceptions are more up-market compacts with a limited zoom range (<6x) or even a prime lens. But these tend to cost almost as much as a low-end APS DSLR.
A separate forum? No real need that I can see. The major manufacturers are already covered.
FWIW, I recently bought a Nikon P6000 compact. This was high end a few years back, but cost me not a lot. No idea what size the sensor is in stupid video-inch terms, but it has more than good enough quality if you don't push the ISO too high. Same goes for Canon's G8, 9, 10, etc. series. Brilliant little cameras!

Pardon my ignorance, but is this a specific class of sensors?
All of DX SLRs are pretty darn close to 1" on the horizontal dimension(24mm, and 1"=25.4mm). My D800 and ancient, awful Kodak DCS 14/n are 24mm on the short dimension and nearing 1 1/2" on the long dimension.
Sensor sizes are expressed in inches notation because at the time of the popularization of digital image sensors they were used to replace video camera tubes. The common 1" circular video camera tubes had a rectangular photo sensitive area about 16 mm diagonal, so a digital sensor with a 16 mm diagonal size was a 1" video tube equivalent. The name of a 1" digital sensor should more accurately be read as "one inch video camera tube equivalent" sensor. Current digital image sensor size descriptors are the video camera tube equivalency size, not the actual size of the sensor. For example, a 1" sensor has a diagonal measurement of 16 mm.

I have to admit I didn’t know why the 1” sensors were so called.
I've never understood the 1" relationship to size but the sensor size charts show it to be one step smaller than Micro 4/3.
Don't really know (or care) why they call it a 1" sensor, but it has about 1/2 the real estate of M4/3, which is large compared with sensors in other compact cameras or smartphones. Below is a few reviews (including images) done by Ming Thein and Robin Wong on a few Sony and Panasonic cameras equipped with the Sony 20mp 1" sensor:

I didn’t either until it came up as a tie-break question in a quiz. Knowing the answer won me £1000.
"Knowing the answer won me £1000."
Sheesh! That's some high-stakes pub quiz. Esoteric questions too.
I think 1" is the diameter of circular hole the reverse CRT (vidicon tube) was stuffed down. A ridiculous way to 'measure' solid-state sensors in any case. Anybody would think the metric system and micrometer had never been invented.
In understandable dimensions; a 4:3 aspect ratio sensor of 16mm diagonal would have a size of 12.8mm by 9.6mm.
