Well, I see the problem though I think, for example, '...contains much
information' is not precise or clear, either. (I think it's generally
difficult to avoid words whose meaning is relative anyway.)

Disagreed. For example, take

"In interspecies transmissions of transmissible spongiform encephalopathies,
the agent has to overcome a species barrier that is largely influenced by
the rate of homology between the prion proteins (PrPC) two involved species.
[...]" [1]

I claim that this excerpt consists of 'difficult language' (for 99% of the
population), but it is /not/ complex, not per se. So I recommend not to
include it in the definition.

> Examples of complex content:

I recommend to remove the 'content that' part since it makes this part too
complex ;)

Well, merging my initial and your proposal and salting it with these remarks
leads us to another definition which I want to bring in as the next
proposal:

"Content is considered complex if it is hard to analyze or understand it.
Examples of complex content include content that

* contains much information;
* is presented very close together;
* consists of many parts;
* uses different presentation styles for similar types of information.

Following these guidelines helps to make content less complex."


Best regards,
 Jens.
