Skype is a proprietary Voice-over-IP program that uses a proprietary protocol. Skype is seducing free software users into using proprietary software, often two users at a time. We do not want to encourage the creation of a Skype compatible client, but instead, we want to encourage you to create, contribute to, or promote the use of free software alternatives to Skype, such as Ekiga, and to encourage to adoption and use of free VoIP, video, and chat protocols such as SIP and XMPP/Jingle.

I have long been annoyed by Skype’s closed platform and have refused to use it despite its popularity. Skype users can only communicate with other Skype users (or PSTN users through SkypeOut) because they do not use an open standard and do not federate with other VoIP providers. This destroys much of the value proposition of using VoIP and ultimately reduces VoIP (in people’s minds) to simply “free/cheap phone calls.” In other words, Skype is helping to hold back an entire industry from innovating.

At Found Line, we use two open VoIP standards: XMPP and SIP. Google Talk provides our XMPP service (through Google Apps) and is used mainly for internal communications. However, Google Talk is connected to the public XMPP network so, just like with email, we can communicate with anyone else using the same standards. Junction Networks provides us with very reliable SIP hosting and allows us to communicate (at no cost) with anyone on any public SIP network. They also provide us with a PSTN gateway (so that we can make “normal” phone calls) and a hosted PBX (auto attendant, unlimited extensions, etc.) all at a very reasonable price.

Unfortunately Jason and I have been too busy to maintain GTalk Profile the way we would like. We plan to streamline the core experience and there are many new features we’d like to add. The 10,000 profiles mark, while not representative of a huge number of users, is a significant milestone because it shows a real interest in what GTalk Profile has to offer. Our goal is to dedicate more resources to the website and treat it like any other project that a client may come to us with.

One of the great things about Google Talk is that it’s built on the open Jabber/XMPP standards (GTalk Profile is actually a website for any Jabber/XMPP user, not just Google Talk users). This means that other organizations using these standards can choose to federate with Google Talk (and amongst themselves). Imagine if you could only send email to people using the same email provider as yourself. This is the current state of instant messaging and the Jabber/XMPP standards, with Google’s help, are slowly opening the world of instant messaging. Now if only some of the other major instant messaging players like AOL Instant Messenger, Windows Live Messenger and Yahoo! Messenger were to start using these standards and federating with others like good citizens of the Internet.
