Blue switches at work - I do check with in those nearby my every 4-8 weeks (truly!) to see if my typing is annoying anyone, so far in (6 years or so on blues or similar) everyone just laughs and says they’ll let me know if it’s a distraction but this far it’s not to them.

Several people have noted to the theme of the fact that typing has quite a rhythm to it, so it’s not like an intermittent or seemingly random noise thus they don’t seem to find it distracting.

By contrast people would be seriously pissed if someone had a desk phone plugged in or a cell phone with an audible ring tone.

Most developers I've worked next to, don't mind it at all, since they focus on their tasks, flow etc. Most non-developers have told me they would prefer I use something quieter. :)
