Then again, if everybody uses a face, a face with a red nose is nice, you'll be noticed. So it's is really a designers question! Do you really want to be (or become) a “brand” or do you want to be a “person”? All important questions, with no one right answer…
I can say that I take your blog seriously because of the professional design and content, and I really believe that that opinion will change once you put your funny wallpaper and holiday pictures into the blog…]]>
For a blog a logo I feel is much more appropriate – for social networking sites like twitter, facebook and flickr having a logo is great but a picture works as well.
using you face pic as your logo you kind of get lost in the ocean of other face pics. And I'm not suggesting that using a logo is going to be easy it's not because of the tiny space you have to work with but it isn't impossible to make it work. There are some logos on Twitter that i know exactly who they are because they use that logo on their blog. And thats the connection, people who use their face pics on their twitter account and have a blog most of the time I don't realize its the same person.
By default I used a picture of myself for my twitter & flickr account because I felt I needed to have some sort of temporary representation there. I want to create a logo for myself as well as for my blog – eventually I will.]]>
A social networks value is contingent upon the transparency of the individuals that represent that network. Openness, honesty, sincerity…those are the qualities that strengthen ANY organization.
And nothing better represents who you are than your picture. (And you'd make your mom happy.)]]>
and i agree about those cartoon avatars, i'm not a huge fan of those myself…]]>
As for photos as logos, I think that has a fair bit of weight. For a long time I've believed (and many write it much better), that individuals are becoming strong brands. Your notion supports that.
Side complaint: Cartoon avatar icons can be grating. I have a few out there, I should think about replacing those maybe.]]>
