Valentine's Day 2007 may be over, but the love endures… especially the link love. Over at Social Signal, we've had a ton of bloggers talking about our Web 2.0 Valentine, and thousands of people coming by to look.

We've been involved in memes that went viral, but never one of our very own. And interestingly, the number one name in meme propagation, Digg, had very little to do with it; a vastly more significant chunk of traffic came via StumbleUpon. Which suggests to me that, just as you can't reliably predict whether something will catch fire, you never know where it will happen, either.

One thing you can predict is that when the blogging world likes something, they're generous with their links. Here are the folks who turn up in a quick Technorati search (other than my personal blog and Catherine's), in more or less chronological order:

• The first blog to link to it: Romania's Ionut Oprea
• Globetrotter Lee Lefever at Common Craft
• The magnificent Monique Trottier at So Misguided
• MapleLeaf 2.0
• The ever-witty Travis Smith at Unvarnished
• Ovidiu at enews.ideo.ro
• Tech 'n Chips Takeaway
• Mathew Patterson at Campaign Monitor (which did their usual fine job with the email version of our card)
• The Max Management blog
• Ken Schafer at One Degree
• The wonderful Beth Kanter
• Sam Huleatt at Leveraging Ideas
• Mack D. Male at MasterMaq
• The superlative Leda Dederich at ScoutSeven
• Best of 3
• Eric Rice
• Bloggers Blog
• Steve Bridger at nfp 2.0
• Territorio creativo
• Gordon Haff at Bit Mason
• kosso's braingarden
• kaerast

Thanks, all of you, for spreading the love. We hope you all were showered with candy hearts, bonbons and (organically-grown) roses.
