This year's Google Doodle for Valentine's Day is actually a link that pulls up a touching YouTube video — "Valentine's Day Google Doodle" — that mostly addresses the meaning of love, but also serves as a not-so-subtle reminder of Google's support for gay marriage.

(Google Doodles are the unique designs inserted above the Google.com search engine to mark holidays and other special occasions.)

The technology website Mashable captures the admirable aspects of the Google video: "the 71-second Valentine’s Day animation on Google‘s homepage tells the story of a boy’s attempt to swoon his crush. He initially turns to Google Search for tips, but everything it suggests doesn’t work."

Without ruining the video's ending, its underlying theme emphasizes the time-honored truth that there's just no substitute for spending time together.

Now onto the political aspect of the Google Doodle: "At the tail end of the video there's a montage of a bunch of happy couples together," Brennan Slattery writes for PC World. "There's a spaceman and an alien; a princess and a frog; a dog and cat; a bookish pair; a cookie and a carton of milk; and two men wearing tuxedoes and holding hands, which I took to imply that they're a gay couple getting married."

Of course, Google is on record as supporting same-sex marriage. In 2008 Google co-founder Sergey Brin blogged about the company's opposition to Prop 8, the California ballot initiative that banned same-sex marriages and now is being litigated.

"While we respect the strongly-held beliefs that people have on both sides of this argument," Brin wrote, "we see this fundamentally as an issue of equality. We hope that California voters will vote no on Proposition 8 — we should not eliminate anyone's fundamental rights, whatever their sexuality, to marry the person they love."
