With approximately 1,897 subscribers at 12:22 PM and about 103 to the milestone, trajectory depends on guest article spike sustainability. At observed 17-per-hour rate: 2,000 arrives around 6:00 PM.

The milestone matters because 2,000 signals real publication status on Substack, potentially unlocking algorithmic promotion and credibility with new readers.
