You can call Esperanto ridiculous, but it's used in all aspects of life. It has a good poetry. I find its internet terms actually better then in some non-English languages. There are several native Esperanto speakers. For instance, George Soros.
> Esperanto is especially bad: it's just a jumble of Germanic and Romance languages
Well, English is a jumble of Germanic, Latin, and French. Doesn't make it bad though (I do love English very much, it's beautiful).
>... that is just as difficult for a native speaker of a non-Indo-European language to learn as the languages it steals from.
You are very wrong. See below.
> In actual fact, English as a lingua franca isn't all that bad. It's a creole (of sorts) and therefore has a relatively simple grammar. The drawback to English is the fact that it's a Germanic creole and that Germanic languages have a comparatively large number of phonemes to work with. It would probably be more useful to most people in the world if a choice were made to go for a creole with a more reasonable number of phonemes, such as Swahili, Indonesian/Malay or Tok Pisin. Until that happens, however, using English is quite a reasonable thing to do.
English is pretty hard language. It's harder to see this fact if you are a native speaker. But here are some benefits in learning of Esperanto vs English:
1) Much simple grammar with no exceptions. For instance, no irregular verbs. 2) Phonetic spelling. https://www.google.com/search?q=english+fish&safe=off&client... 3) Consistent word forming. For instance, compare: tree/forest/gamekeep vs arbo/arbaro/arbaristo, where 'aro' means collection, 'isto' means professional. 4) Tons of other goodies, I won't write it here.
