Most days I have a limited amount of time to spend on nostr. No time for little bitch ass hoes in my timeline or notifications 😂 
To be fair, I chose 1 month somewhat arbitrarily but it’s been my consistent guideline. I figure it’s normal for people to take time to unplug, go on vacation, get busy with projects, etc. A week or two offline, to me that seems normal. But if it starts pushing towards a month or more, then to me it seems like you’ve got better things to do, and that’s perfectly fine and your prerogative, but I don’t want that npub being dead weight, that’s all.
