He may also have some friends and guests join. \n\n\nCharles Star is an attorney in Brooklyn, the host of [Hostile Witness](https:\/\/www.soundcloud.com\/hwpod), a panelist on [ALAB Series](https:\/\/www.alabseries.com\/) and the guy who did most of the talking on the late [Mic Dicta](https:\/\/soundcloud.com\/micdicta). He tweets at [@ugarles](https:\/\/twitter.com\/Ugarles) (and has a reddit account he almost never uses). He writes about legal issues from time to time and has bylines in Vice, Slate and a bunch of places that no longer exist. (He'd probably appear on your podcast.)  \n\n\n**What is Reddit Talk?**\n\nTalk allows us to host interactive sessions with podcasters and users of the community can join in and interact with the speakers in real time from either new.reddit on desktop or though (an official) Reddit app. A Talk can handle up to 30 different speakers and up to 100k listeners in the audience can tune in at the same time.\n\nYou can learn more about Reddit Talk from the user guide [here](https:\/\/reddithelp.com\/hc\/en-us\/articles\/4404349195284-What-is-Reddit-Talk-) .\n\n**Ask Away!**\n\nIf you can't make it live at that time, you may leave any questions you might have  as a comment on this announcement post and we'll try to pick some to read during the Talk. A recording of the Talk should continue to be available here after it concludes.\n\nYou can tap on **Follow** on this post if you'd like to receive a reminder notification when the Talk will begin, if you'd like to come ask a question live.","send_replies":true,"spoiler":false,"stickied":false,"subreddit":"podcasts","subreddit_id":"t5_2qh1d","subreddit_name_prefixed":"r\/podcasts","subreddit_subscribers":2322456,"subreddit_type":"public","suggested_sort":null,"thumbnail":"self","thumbnail_height":null,"thumbnail_width":null,"title":"Have questions about recent Supreme Court decisions?
