Hypertext pragmatics: Hypertext acts?

By analogy with speech acts, writing acts, text acts, hypertext acts could be defined. An example:

1. Search by
   1. Address (URL in WWW)
   2. Browsing (link by link)
   3. Search machine

2. Interaction with query and other programmes (via HTML and CGI or Java), in order to conduct transations:
   1. Search databases
   2. Register information
   3. Commit to a course of action (e.g. conference registration, purchase)

3. Interaction as author vs. interaction as reader vs. interaction as server operator

Metaphors such as `querying' a database or an expert system have become technical terms in their own right.

Assumptions about accuracy, truthfulness, reliability, safety, and privacy are involved.
