At the SoundLot you’ll discover a group of like-minded folks to connect with locally. The site boasts your ability to build relationships with local musicians, local artists and filmmakers to build an active community online that you'll hopefully be able to take off line to collaborate on projects, shows, etc.
I like the site. It's super simple and clean - not a whole lot of navigation to figure out what you need to do. The concept is simple. It's apparent the idea is to build professional artistic relationships to learn from each other allowing those who participate to further their craft beyond what they could alone.
The site offers user generated resources, tips, other sites to check out and more. If you're looking for a place to interact with others facing similar things as you, then the the Soundlot is the right place.
Groups are split up by the three main categories, music, art, and film and beyond that there are local groups by city.
Here are some of the features highlighted on the site:
-Field specific profile sections (music, art, film)
-Join local and regional groups
-Shared group documents (to keep info that the community can use)
-Rate posts (reward the best contributors)
-Share your bandcamp, soundcloud, flickr, deviantart, youtube, vimeo, twitter, and personal site
