What's your suggestion for product public beta

Hi, All, We will launch our product for public beta this week. In order to get earlier adopters, I list something I need to do: 1, Create product LinkedIn page - done 2, Create product twitter page - done 3, Create a post in Reddit sideproject subreddit - launch day. 4, Create a post in Indiehacks - launch day 5, Create a post on my own LinkedIn - launch day 6, Create a post in Facebook group related to data analytics - launch day 7, Invite some Product hunters to try our product - after launch day 8, Monitor related subreddit to answer questions and DM with our product. Are there any other ways we can get earlier adopters? Thanks and Regards, Tony
