October is Breast Cancer Awareness Month, a time when you’ll see more pink products than any other time of the year (unless you’re a Mary Kay salesperson). Although a lot of “pinking” will happen in the corporate space, this is a perfect example of a meme I’d like to see spread around the microblogging sphere.

We’ve covered some large, sweeping memes in months past, like mangavatars and 080808, but this meme has the potential to spread awareness and help save lives through education.

Take a moment to consider adopting a pink avatar for the month of October and help spread the word.

And, for those of you who run your own blogs or websites, take a look at Pink for October, an effort to get websites to Go Pink during the month of October to bring attention to Breast Cancer Awareness Month, get people talking about breast cancer and raise money for research.

The Pownce community is a vibrant bunch in its own way. In terms of its scale, the Pownce user base is nowhere near the size of Twitter, but its users compete based on creativity and their passion for the Pownce platform.

One unique trend on Pownce is that the users have created their own themes for each day of the week as a way to tie the community together. If you are new to Pownce (see our Pownce review) or are looking for another way to participate within the community, here is a quick way to get started with a post for each day of the week (courtesy of the Pownce wiki).

#080808 was a meme that made some headway across different platforms, with Flickr doing their own 888 campaign and of course all of the Twitter fanfare, but since I’ve begun microblogging I’ve never seen a meme take hold like #mangavatar.

I first heard about it on Twitter when I was Hahloing through my timeline on a Friday evening, noticing that most of my friends had recently changed their avatars to cartoon manga characters. As it turns out, chatter on Twitter about mangavatars goes as far back as three months ago (according to Twitter Search) when Mystiria (@mystiria) uploaded her new avatar and tweeted about it to her friends.

The site everyone is using is called Face Your Manga, and it allows users to select from an assortment of different features and accessories to create a manga replica of themselves.

The phenomenon seemed to hit the mainstream microblogging communities only recently as now is when I’ve seen the most real-life photographs being exchanged for Japanese manga cartoons with similar likenesses.
