Please develop a very simple plugin for social media accounts. There are a million available. Make it a simple link for each social network to the user’s actual profile page. Perhaps make the icons several sizes.
I hate downloading (paying) for such a simple widget on every site I design. I don’t use free widgets on my clients site because they may not work in the future. That is why I subscribe to WPMU. I can upload the widgets and feel confident in their longevity.
Please consider this heavily.
