Remember that Fliqlo is Flash-based. It has an outdated, unsecure version of Flash embedded in the app package -- version 10.0.32, I believe.
I'm not tech savvy enough to know if this is a security risk or not, but given that Flash exploits on PPC have remained unpatched (and will, as Flash is deprecated on PPC), I know that I'm not putting this on my PPC.
I wish there was a non-Flash version of this for our old macs!
