To me Wikipedia is like a Dictionary and Encyclopedia all rolled into one.
About anything you would need to know all rolled into one.
Anytime I'm stumped and don't understand something or a word I just Type into my search bar the word or words and hit the space bar and then enter and it goes to Google on my Mac Safari Web Browser on my Macbook Pro and Macbook Air Computer and it finds whatever it is I am looking for to find out about and usually the top pick or the second or third one down in the Goggle response has Wikipedia's Definition of whatever it is I'm looking for.
My main first resource..
Reuters was the first one I typed in this morning.
You see them everywhere.
Fourth one down..
The first thing I learned in all this when I first started with computers and the web was..
Research research research..
Pretty much answers everything.
Getting past the biased and slanted and paid responses making money and luring you takes some time to learn but it's all here..
The profiteers and hustlers and con men and salesmen and money makers and schemers are everywhere all over the web.
Also tons and tons of legitimate stuff..
Amongst all this we find our way..
I also like my Mac spell check and definition on my computer at a glance..
I just highlight whatever word or words it is I want to check on or it underlines it in red for me and I hold the control button and then put the curser on it and click and it gives me the spelling and definition instantly..
