I think its a bit of a chicken and egg, right now a good portion of the content is people talking about nostr and devs. No complaint from me but thats not the content most people want. But this will change as people join. This take is also skewed by my follow list and i don't look at gloabl so i could be totally off. Related to this is discovery of other accounts, without looking at global its tough to find related accounts that you may be interested in.
