Does an Alernative to seclists Exist?

Full Disclosure on seclists (https://seclists.org/fulldisclosure/) used to be a nice source of information for some vulnerabilities that could potentially exist within our network. As such, I haven't really seen much from FD over the past couple years and activity has really slowed down for some reason.

Does anyone know of any decent alternatives? Maybe a Twitter handle I can scope out? Something short and concise like FD was what drew us in in the first place, and the information was very useful.
