Do exactly what Ping was doing.
Your features are far to limiting. I used Ping daily all day for a long time. You've gutted it! Why? Compared to Ping Seesmic offers almost nothing. Sad.
We’re working on adding features and there’s a few distinct features (multiple twitter, scheduling, link attachments) that we provide. As mentioned in our blog, it was a challenge for us to maintain the current state of Ping.fm, so we took the course to redo Ping. We appreciate your patience and support and will log this as general feedback.
