To be frank, it is kind of a ghost town compared to years ago, especially considering a lot of people are basically home all the time. Still, I shall abide by your directive.
A lot of people must be aloof from forums then, because it's not like a new Trad Catholic forum has supplanted CI.
Fisheaters has more posts, thanks to its age and "past glory", but it is a decayed shell of its former self. It has a small fraction of CathInfo's traffic today.
I guess we all need to get used to this common question/answer pair:
Question: "It's so SMALL! Where is the real place to be?"
Answer: "There isn't one".
This applies to Traditional Mass venues. If you're looking for "The Old SSPX" having "old SSPX" numbers, you're out of luck. You can either have the old SSPX faithfulness and zeal (the Resistance) and endure small numbers, or go for "popularity" and basically immerse yourself in a watered-down, compromised Indult "Latin Mass" community.
If you want BOTH fidelity AND numbers -- better have a time machine.
P.S. CathInfo isn't at the top of Google search results by accident. They still have Fisheaters as #1, but that's due to a flaw in the Google algorithm. Let's just say they give too much credit to "past high school trophies" rather than one's current physical shape. They give extra points for older domain names. FE has been around a few years longer than CI. For that matter, they have Catholic Answers in the Top 3 results for "Traditional Catholic forum", and they don't even *tolerate* Tradition, much less any groups unapproved by Rome.
But I've done the math, compared "online users" at various times, total post count on both forums (and again 3 months later) -- and the math proves that Fisheaters has less than 1/3 the traffic of CI now. All the good people left for CI or one of the FE spinoffs years ago.
