Best Technology Subreddits
Tech on Reddit splits fast. r/technology and r/gadgets cover the news and the devices, r/Futurology argues about where it is all heading, and the comment sections are often more useful than the articles themselves.
Then there are the hands-on corners: PC builders who will check your parts list, developers trading code and career advice, Linux users, sysadmins and security people. These subs reward questions that show some effort.
The list below mixes the big news hubs with specialist communities, so you can follow the headlines and still find a place to ask a real technical question.
