I have accounts on dozens of web sites. New ones pop up every few weeks; old ones are seldom purged.
I use these accounts every day:
I use these fairly often, but not daily:
These see little activity, but are not abandoned:
- Project Euler
- Stack Overflow
I never use these:
I really ought to delete accounts in the latter group, but 1) it’s not always possible; and 2) I’m lazy.
Update: I deleted the ones I could delete. The others will linger, abandoned & ignored.
