It's solving a tiny problem that annoyed me for many years: find a way to have unique keys for entities that don't have an obvious one without displaying their primary key as a number.
base 10 is not the best representation here.
feedback welcome!
I have never in my life typed out a URL (with an id, google.com and stackoverflow.com don't count).
I don't put naked ids alone in spreadsheets. If, once a year, I do need to make a spreadsheet, I put full URLs there.
Length of these ids is comparable to that of base-10 numbers and neither are "very long".
And so on.
For further context, we are working on online campaigns (petitions, sending emails to elected representative...) and everything has either ids (numbers) that we generate (a campaign, a action, a supporter...) or given externally (eg. the elected representatives or vote reference).
Most of these ids are in the 1k to 100k range, that happen to often be the same range as the number of actions taken or emails sent) and mixing these KPIs and ids on the same lists happen to be confusing for users.
It might be that we shouldn't try to put these ids in lists and summaries, but they are super convenient there sometimes and unavoidable when exporting to excel, so dxid was my solution to work around our potentially poor ux design ;)
