One of the biggest early draws to Google's new social network Google+ is the ability for users to break their list of friends into "circles" which each have their own level of communication. For example, if you want to post a message just for your old college buddies and not your co-workers, you can select the appropriate group and share that content without having to worry about the wrong people being involved in the conversation.

Diglo, a social network specifically aimed at file sharers, takes the same approach to uploading and downloading content. Rather than just being a web-based locker like RapidShare or Megaupload, Diglo lets users set up a profile that can have as little or as much personal information as they like, and then they can begin sharing files with as many or as few people as they choose.

Files can be made available to the public (links for anyone on the web, not just Diglo users), or they can be available to as many individual users as the uploader chooses. Public files uploaded to Diglo can also be browsed and downloaded at will by users.

The site can even be used as a personal backup for files, and users can upload as much as 15GB of content that is private and available to no one but themselves. Only 10GB of the total allotted storage can be used to share files at any given time.

A sign that this is truly a site for file sharers, Diglo also has FTP access for all of its users, an in-browser music player with playlisting features where users can just drag and drop files to listen to within the site, and a "karma-based" upload and download scheme.

When a new user signs up, they have a 15GB premium account for the first 30 days. Users receive 10 points every time someone downloads a file uploaded to their account, and 10,000 points equals 1 month of free Premium membership. Naturally, all uploads have to adhere to copyright laws and Diglo's terms of service.
