I'm looking for some software that might be described as a blog (or diary) but I don't really want/need it to be web visible. It's more for creating a 'timeline' of events over the years, I want to be able to cross-reference stuff and to have links to external stuff.
The requirement for links and cross-references does sort of suggest HTML, that would be alright, but I want ease of creation and simple formatting rather than an elegant web presence. Ideally the format would be plain text or HTML or at least the content should be possible to export in one of these formats to enable content to be preserved when/if the software to generate it has gone.
Any ideas, suggestions, places to look?
