Web development. Is it good choice (event-driven programming)?

    I don't even know what "event-driven" means, in the context of a web
application.

    Are the events the HTTP requests? If so, then how is "event-driven web
app" different from "normal web app"? If not, then what are the events?

Often, a event-driven webapp might use Ajax, or Cometd to push/poll
events between the server/client. Also, Spring Web Flow is considered
event-oriented. The actual HTTP request isn't the event, but instead
describes the event (the user clicked on button A, or the user clicked
on button B).

Event-driven is often just a way to explain the information flow
within an application. If you get down to it, all programs are finite-
state Turing machines.
