I follow the #ActivityPub hashtag and see this same msg for the 10th time or so and it becomes a bit spammy. The best way to get attention is to ask concrete questions that people can help with. There are also a number of places on the web to consult or interact with like https://socialhub.activitypub.rocks dev community, the W3C #SocialCG mailing list and AS/AP repo issue trackers. There is the #FEP process at https://codeberg.org/fediverse/fep and fedi-resources at https://delightful.coding.social
