SILC - Secure Internet Live Conferencing

There have been some heated discussions here following the latest bugs found in cryptocat.

Several people pointed to SILC as an existing option for secure group chat.

But SILC has its own share of problems: https://we.riseup.net/riseup+tech/problems-with-silc

Maybe the people who argued against cryptocat and similar efforts could shed some light on what they think of SILC.

I wonder if SILC's fundamentals are similarly flawed. Or is the recent rise of interest in secure communcations a good opportunity to revisit SILC?
