I'm only a few months into this whole blogging thing, but I've noticed that most bloggers predominantly write in one or two of several formats:
The Update: posts about babies, news, birthday parties, first days of school; usually text and pictures
The Travelogue: chronicles vacations, trips to the zoo, outings to the grocery store; usually text and pictures
The Photo Essay: tons of pictures, not much text
The Life Vignette: little daily happenings or trivial but sweet moments; brief and usually include a picture
The Op-Ed: passionately speaking out on issues from politics to knuckle-popping; mainly text
The Journal Entry: detailed and introspective; often contains TMI or info no one else cares about (except that we actually do, since we're all blog-stalkers)
The Essay/The Personal Narrative: often funny and always wordy, these posts are usually predominantly text
The Projecteer: includes all entries dealing with cooking, crafting, organizing, decorating, landscaping, etc. etc.; usually consists of pictures and captions/descriptions
Do you recognize yourself in any of these categories? They are by no means comprehensive (I didn't include the "Look How Much Better My Life is Than Your Life" category because it can appear as a subcategory to any of the above), so feel free to add your own.
I think my blog is a smorgasbord of most of the above--kind of like I have multiple personalities and all of them insist on making their voices heard in my various posts. My existence can be a manic one, but I find peace through balance.
I've been neglecting my blog lately, but stay tuned for a "Travelogue" entry chronicling our awesome spring break trip to California.
