This is certainly only in rumor stage at this point, but Business Insider is reporting that popular tech blog network GigaOm may be for sale.

Nicholas Carlson reports that a couple “insiders” have said GigaOm is “on the block,” with one saying the company has been “flirting with Bloomberg and Dow Jones.”

Earlier this year, GigaOm acquired PaidContent, another industry publication.

Time is already republishing PaidContent articles. If GigaOm is really looking to sell, perhaps Time Warner could be a potential suitor. GigaOm also partnered with TheStreet in 2010 to share content and audiences.

GigaOm has yet to respond to our request for comment.

On the company’s about page, GigaOm claims to have an audience of 5.5 million monthly unique readers. While Compete’s numbers are often much lower than publishers’ internal analytics, the firm had GigaOm at 219,288 unique visitors in the U.S. for the month of May. Here’s a list of some of the top industry publications and their numbers.

For perspective, Business Insider itself announced that it hit 15 million uniques yesterday (compared to Compete’s U.S. count of 2,681,606 for May), and WebProNews had 5.2 million in May (compared to Compete’s count of 2,239,178 in May).

GigaOm isn’t the only industry publication rumored to be for sale. Rumors of talks between Mashable and CNN have recently been back in the media as well.
