Mike,
Superb job in creating Sonic Junction. I hope you have great success with this.
As Bruce mentioned the site is very clean. I like the fact that you have given the ability to upload video, audio, pictures right from the text box area natively into your site. It keeps down the effort of posting to YouTube, or SoundCloud, or Picassa, then re linking. Plus I have seen when someone does a remote link, chances are later the native site will have missing pictures, etc over time as the hot links ineviteably change or are altered sometimes.
I noticed you have a personal blog. Will regular members be able to have a blog?
I would like to have the ability (If Duke has time) to share a short video of material I'm working on and get his feedback, like a remote private lesson. I'd pay extra for this service if he had the time and your site had the ability. I could envision a private link, like YouTube has a method of only being able to see the video if you know the link. Or if the member wished, he could have the video public and allow other members to give feedback as well.
It will be very interesting to see how you grow this site. It is a unique and fresh concept. As a businessman in the technology industry, I am very intrigued at what you are doing. Building revenue for the artists with this concept must be a creative and challening effort. I believe this type of forum will increase the artists brand awareness, as well as trigger sales to older recordings and promote live shows, (I would recommend there is a link to this stuff somehow for the artists). It's all in line with the new Social Media world we live in, and Sonic Junction is cutting edge.
PS: It's a great diversion to FB with a smaller subset of people with the same interests.
