The tense-space system is a good example. By default, a sentence like "mi tavla"/"I talk" doesn't convey any temporal information. But you could add a tense particle like "pu": "mi pu tavla"/"I [past] talked". But that doesn't really tell you how long ago it was, so maybe you want to add "zi" to indicate that it was recently that you spoke: "mi pu zi tavla"/"I [past] [recent] talked" which might be interpreted as "I was just talking". But where were you doing that? Perhaps you were just talking downstairs, so you'd add "ni'a" to indicate that it was below: "mi pu zi ni'a tavla"/"I [past] [recent] [down] talked" -> "I was just talking down there". But maybe you do this all the time? Let's add "ta'e" to indicate habitually. "mi pu zi ni'a ta'e tavla"/"I [past] [recent] [down] [habitually] talked" -> "I used to talk down there all the time". But maybe I want you to know it was kind of a problem or that I did it too much? In that case let's add "za'o" to indicate that the event went on too long: "mi pu zi ni'a ta'e za'o tavla" -> "I used to habitually talk down there too much."
I like this example because: 1) I've only used four or five of the 28 sections of Chapter 10: Imaginary Journeys, which concerns the tense system, 2) this is only the tense system, not any of the copious other systems Lojban has 3) this shows you the kind of particle-soup that I think Lojban can easily devolve into, and 4) eventually, a real Lojbanist will arrive and correct everything I said above, which is an important part of the real flavor of the language. Being less snarky, my suspicion is that there is a real art in choosing which information to add, since none of it is obligatory (unlike English), and it is quite possible to add information in Lojban which would require additional clauses in English, that makes it an interesting mental exercise to interpret.
