I also own (example again) EWiDS.com which doesn't say nothing but is a direct abbreviation of the above. Easily pronounced and just 5 letters.
Which domain name yould you go by and why?
Many thanks for your expertise and experience in this.
Letters likely won't stick in memory as words.
Egads! It's a toss up! Easier to vocalize versus memorable.
Maybe longer for vocal - if memory is the concern - and shorter + longer on printed/on screen for ease/option of typing?
