That'll be the pownce
Get your latest web2.0 fix with pownce. You already have a twitter account and are probably updating every 20 seconds or so. Now you can add in the ability to share files and links. Whoopee. Like all these sites it relies on you inviting all your friends so check your inboxes now.
There are already a spate of sites giving you less than ideal solutions for posting to all your microBlogging sites. Now we have another landgrab situation with all these sites starting up their own sites and protocols getting their own bunch of sites. What we need are more standards for this type of thing and a bit more openness. Most of these sites are built on open standards such as http, TCP/IP and javascript but they all want to lock you in and totally miss the point of the heratiage of what has got them to this point.
The jabber.org site was dedicated from the start to define the XMPP protocal for open instant messaging with one of the fundementals being server to server communication and so as people like google and gizmodo start to adopt this they instanly get that compatiablilty and the barriers to truley open instant messaging are slowly worn down. Think back to the time of Compuserve and AOL where you could not even send an email between the networks and this is how we are progressing with the current spate of online applications.
There is some light as some sites open up thier API and also provide RSS feeds but this is only part of the picture. If they had specified a protocol between themselves then from my twitter account I could also add in contacts from other services simply by adding names such as [email protected] or [email protected] and everything would be easy.
Add in OpenID to this and you could have a simple method for making contacts. I add you to my openID account as a contact and set you up to be able to contact me by electroinc forms, read my personal posts or photos and post to my public spaces then as I add more services you automatically get access to those.
