Leaving out particles before adjectives/verbs?


I haven't really read any guides on Japanese grammar (except occasionally
looking up pages of Tae Kim's when I need something explained), so I became
quite confused when I saw things on Twitter like これすごい (instead of something
like これ **は** すごい). I also noticed people seem to do the same thing with
verbs, like saying アニメ見た instead of アニメ **を** 見た (that's probably a bad
example, but it's the first thing I could come up with).

So what is up with this? Is there some sort of pattern behind it I can follow?
At first I thought it was something done in a casual setting (like a Tweet),
but I feel like I've seen the same thing done in more polite Japanese.




Colloquialism often amounts to simplify things by contracting or entirely
omitting supposed-to-be-easily-understood elements. Thus those particles are
the victims of such tendency. It is not recommended to follow that in formal
documents. Does this make sense?
