I am sceptical about ranks/metrics.
Someone informed me that my podcast was rated highly in a database of science-related podcasts from India. It seems perplexity AI also shows similar results (see images)

My learning: Open-source, non-commercial, individual ventures can have some impact
Let me reiterate :
Value of knowledge cannot be captured entirely using metrics, ranks, views, likes and number of subscribers on social media platforms.
The quality & depth of engagement are hard to measure & the world is nonlinear
I have done zero adverts./marketing 😀
But I must thank
a) ppl who have been guests on the podcast. They have been very generous with their time & knowledge.
b) listeners who engage with long-form content (even when I talk solo😆)
They deserve more credit.
Science zindabad!
