Viideo citation and blogging frustration. A few months ago, I wrote about the tragic inaccessibility of audio and video content on the web. Today, while trying to summarize one of the key insights that came out of the BloggerCon conference I attended this past weekend, I was again reminded of this problem. The issue I want to highlight is the gap between what technically proficient users of the blogging medium (or indeed any kind of web authoring) can achieve, and what average users can achieve.

Adam Bosworth on Event Systems at HPTS.

Adam described 4 styles of event / pub⊂ systems that he think will emerge, each with different scalability characteristics

1. Enterprise Application Integration. The average enterprise has about 5000 applications that are one by one integrated into becoming event generators for the EAI portals. Important here is that the data model needs to be flexible as you do not know what apps will need be integrated tomorrow. Medium number of publishers, medium number of subscribers.
2. Business to Business. A limited number of customers (up to a thousand), and at most 2-4 applications that are receiving the inbound events. Transaction rates are low.
3. Mobile. The mobile operators want to start using your locality information to start providing targeted information to you in a style similar to advertisements in Minority Report. You get to subscribe to 'send me an sms with Gap's items on sales when I enter the xyz mall'. Lots of temporal events with location information, and potentially many subscribers
4. RFID. The volume of this stuff is going to be unbelievable, but many of the event may be discarded given that there is no change in location
