Its main strength- or weakness- is a lack of a clearly-defined purpose. It mixes factual articles with fiction, thoughts and opinions, humor and meta-E2 content. E2 has (or had) its own style.
Although still being added to today, E2 is long past its heyday. Most articles were written between 1999 and 2001 and now it's more like a snapshot of the time than a living thing.
When it comes to humor and personal writing, the community is definitely more indulgent towards established users. Perhaps this is why E2 has declined from when everyone was a newbie. Unless you want to write Wikipedia-lite, who wants to bother with the politics?
