@Southside and others think dweb needs a different default port than 8080 and I agree, but what? 
Unless someone who actually knows about port allocation tells me I should stick with 8080 I’ll change this soon and we’ll see how it goes but it should be fine afaik. 8080 is such a nice number though.
I’m still open to suggestions, but the guidance on Wikipedia seems to be pretty straightforward. I’d like to choose a number that is both memorable, cool 
and unlikely to be in use. Unf. those don’t all go together.
A little research suggests:
- stay away from <1024 (root required) and >49451 (dynamic/private)
- search for any candidate to avoid commonly used ones
- starting with 8 kindof maybe implies HTTP
Some tempting options:
- 1618 (alluding to the Golden Ratio 1.618)
- 4325 (x10^16 is the number of configurations for the Rubik’s cube)
- 1974 (the year the Rubik’s cube was invented)
- 9110
- 5550 homage to the wonderful 555 Timer chips
- 5537 first four digits of the DMS coordinates of Irvine, Ayrshire: 55°37’9.84" N -4°39’18.29" W
I could go on but ten minutes if probably long enough!
I quite like 5537. It doesn’t show up in use anywhere is memorable and not an obvious number for someone to choose as far as I can see.
