A few weeks ago we told you that eBay was in talks to buy StumbleUpon. And then nothing happened for a while. Well, stuff happened, but the biggest announcement involving eBay was probably the new Firefox Companion for eBay.

Now the Wall Street Journal reports that the talks are on, and that auction company could be prepared to shell out $75 million for the social web discovery service. There's no final agreement on the table yet, and the deal could still fall through.

As Duncan Riley at TechCrunch points out, this an interesting move for eBay. The company has already purchased Paypal and Skype, but those are both companies that can be integrated into an online auction service. StumbleUpon lets users discover new websites by clicking a Stumble! button on their browser toolbar. Unless eBay wants a new way for users to find random junk for sale (which you can already do pretty easily), this seems like a departure from eBay's usual offerings.
