@dblaze09 !loadaverage had the Nodeinfo plugin disabled for a several weeks, I re-enabled it a few days ago after I added the proper indices to the "notice" table.
The !gnusocial Nodeinfo plugin advertises software as "gnusocial". When Fedilab checks Nodeinfo, it expects "gnu" for some reason.
As far as I can tell, neither the original @chimo's plugin, nor the included one ever had this value. Weird.
