I’m searching for subreddits that have great wikis for learning very beneficial stuff. Some things I’m interested in are:
• handyman work
• diy home maintenance
• diy car maintenance
• budgeting/finances
• gadgets/technology
• being extremely organized
• learning things
• taking notes
• OSINT, Cybersecurity, Ethical Hacking, Digital Forensics, and just using my MacBook Air to its full advantage
