Yeah, I've noticed a few bio trends as well...
For example, I see so many people who just pack every single possible detail about their character into a huge paragraph... no line skipping or even noticeable spaces between sections. This may be just for a complex character with a lot of roleplay info, but a few people seem to overdo it a bit. There also appears to be a rise in "wolfspeak" terms, as well as fancy complicated words.
Information also seems to be more literarily organized (if that makes sense). For instance, instead of just typing:
Name: Colonel Henry IV
And instead is written like:
He bares the name of Henry, passed down from a long line of the alias, as to take the rank of Colonel.
Or something like that. It might just be preference, but it seems to be a lot more popular now.
