Name: webOS Users*
Description: Those currently using any form of the webOS platform.
Status: TV users can be guessed from LG sales figures in the millions. It is very difficult to estimate numbers of legacy & open webOS users. From a potential maximum of 500,000, the actual number must be much less. 750+ donated to the ACL Kickstarter. The self-declared count on the old forum was 335. Members of the discord group are currently @138. Some new legacy users are still appearing! Any information on user numbers will be gratefully received and can be posted on this thread.
