I’ve only got accounts setup on twitter, FriendFeed and identi.ca though. The other benefit of a using a tool like Twhirl though is that you can also manage multiple accounts simultaneously. So you can have a personal and business account the same services.
The other benefit of using an application like Twhirl to manage your twitter account is that it assists you in quickly sorting and separating your replies and direct messages from other twitter users (tweeps).
Anyone have an idea about that?
