Yahoo is confirming all kinds of acquisition rumors this week. Well, at least two. Yesterday, it was Qwiki, which the company acquired for somewhere around $50 million, according to one report.

Today, Yahoo has officially announced its acquisition of Xobni, which was rumored over a month ago.

A Yahoo spokesperson tells WebProNews in an email:

We have acquired Xobni, a company dedicated to smarter inbox and contact management. The Xobni team developed a platform that is smart and intuitive — it processes contacts the way you do naturally in your mind. Xobni instantly provides a full view of each contact, complete with a photo, job title, company details, and email history, as well as updates from Facebook and Twitter. This acquisition will help us make improvements to Yahoo! Mail, Messenger and our overall communications offering on both desktop and mobile.

Xobni continues on tis blog:

We know that Xobni products have woven their way deep into your daily life. Many of our product improvements have come as a result of your enthusiastic, detailed feedback. We often hear customers say “I couldn’t live without Xobni.” Not to worry — we aren’t pulling the rug out from under you. If you’re using a Xobni product today, you can keep using it. To find out our plan for each product, please check out the FAQ. Of course, soon you’ll be able to use Yahoo! products with Xobni goodness baked right in.

OK, back to the announcement. Did you ever meet someone who truly “gets” you? That’s how we feel about Yahoo!. The power within every Xobni product is that it responds to how you communicate. Every day you demonstrate who and what is important to you. That can benefit not just your inbox or smartphone, but the many services you use. Yahoo! gets that, and they want us to use our platform to make many Yahoo! services better for you. This is just the type of gig we’ve been preparing for throughout our history. We look forward to letting the results speak for themselves. Stay tuned….

According to All Things D, who first reported on the rumored acquisition, the price is “upwards of $30 million”.
