I am commonly found code golfing in:

• Perl 6
• brainfuck
• Befunge-93
• Python 3
• ><>

• Hexagony
• Befunge-98
• Brain-Flak
• Lost
• Gol><>

Planning to learn:

Posts I'm proud of:

• Cyclic Levenquine (Gol><> 167 bytes)
• Golf you a quine for great good (Hexagony, Lost)
• Klein Topololyglots (37 bytes)
• Geiger Counter (Lost, Hexagony, SMBF)
• Halting Problem Paradox (brainfuck, 4376 bytes)
• Mutually Exclusive Quines (><>, 42+42=82 bytes)
• Hello, World! (Hexagony, 29 bytes)

If someone comments on a question "I wish there was a brainfuck solution", I feel obliged to provide one.
