I have a single thread on some other forums where I post about updates in my guitar/mixing/daw blog (anywhere from twice a week to once a month), which has been well received. A sort of in-forum RSS but that usually adds discussion and great tips and follow-ups from other forum members.
On reddit though I almost got banned from r/guitar for infrequently posting links to my own content (interspersed with links to other interesting stuff).
Let the voting commence!
Your comparison of guitar interfaces for the iPhone was EXTREMELY helpful, and i ended up buying the Apogee Jam as a result. Useful information is useful!
