There's an ubiquitous plugin for blogs that allows users to connect with what seems like 200 different web avenues. (Digg, StumbleUpon, etc.) Now, I'm convinced this "Connect however you want!" trend will die soon enough and the frontrunners like Facebook, Youtube, and Twitter will be supported and nothing else will. The blogosphere simply can't embrace that many core technologies without diluting the message. I enjoy when companies take Facebook's, Twitter's and Youtube's logo and integrates them into their website visually. EX: White background / Buttons in black silhouette until hovered over. My question is this. What core applications and functions must corporate blogs support (assuming they have supporting material)? Vital: -Facebook -Print Layout -Email to a friend Recommended: -RSS Feed -Twitter -YouTube Emerging speciality applications: -SmugMug (vastly superior to icky, icky Flickr) -Vimeo (nice colorful interface and knowledgeable community. YouTube HD is a step forward, but you really have to manage feedback.) I'm hoping RSS feeds become mainstream. Leopard spoils me because RSS feed management is built into Safari and Mail.
