Is latency a pro or con?

I'm confused here. In "Pros and cons", it is said that the main advantage is the speed at which an AJAX application runs and responds to user interaction; due to the client-side scripting taking place which reduces the amount of per-interaction network traffic. Later on in "Criticism", "critics focus on the technical issues AJAX raises, beginning with network latency" (with this link to someone's blog that goes on about how AJAX is no good because of latency). Wha...art??? -- Jin 23:06, 19 August 2005 (UTC)

That blog post talks about usability problems with Ajax. I have updated the critisicm section. --Sleepyhead 13:20, 20 August 2005 (UTC)
In terms of latency itself, it's a con -- as in, the fact that things that used to be instant are now dependent on the speed of the network might be confusing to users. (The advantage that's discussed in the article isn't related to latency per se, but rather, to the slowness of a browser needing to render an entire page when updating a small section of the page would do just fine.) The latency issue DID highlight a confusing part of this article, though, namely that the distinction between what is a "con" (in the pro/con sense) and what is a "criticism" is a little muddy. Thus, I combined the two sections into "Pros, cons, and criticism", and then clarified the latency issue a bit. Jason 16:38, 21 August 2005 (UTC)
Even now I think the criticism paragraph on latency is a bit on the negative side. I've been doing some research, and it seems that network latency is just something you need to consider carefully during AJAX development. If make a proper interaction and technical design, web applications will be more responsive. If you make mistakes, usability and responsiveness will suffer. Is it OK if I try a small rewrite of the latency paragraph? Jep 18:35, 4 September 2005 (UTC)

Search Engine Accessibility

The entire Search Engine Accessibility section seems to be an ad for Backbase, something I realized after I removed the spammy Backbase link that ended the section. I'm deleting the entire section for now, as the entire rest of the Ajax article makes the point the section is making, and doesn't do so as a pretense for laying the foundation of a "problem" that's solved by the good folks at Backbase.

Jason, I think Search Engine Accessibility is a very relevant topic for AJAX applications. I have added the link to provide more indepth information on the topic (the article is not a BACKBASE plug, but a contribution to a generic AJAX problem). If you know otehr articles about this topic as well, please include them. Let's be open, and cooperative instead of just deleting contributions. If you like you can contact me at info at backbase dot com. August 31, Jouk.

I'm happy to be open and cooperative, but Wikipedia isn't a manual, it's an encyclopedia. In other words, saying that Ajax provides challenges for search engine accessibility is appropriate, but providing detailed information about how to overcome the challenge is better left for a computer manual (perhaps the Wikibooks contribution that's linked at the bottom of the entry).

OK, I just read over the addition about search engine accessibility, and it really seems like it's trying to be a manual. It would be just as easy to flesh out the pros/cons section so that the line that talks about bookmarking problems extends this to be a search-engine problem as well (since they're the same problem); it doesn't feel like WP's the place to go into this much detail on proposed solutions, though.
