Demi Moore, Ashton Kutcher and Twitter

One of my biggest weaknesses? Following the messages couples publicly share with each other on social networking sites.

Calm down, I'm not being cruel. Sure, there's a certain voyeuristic quality to the obsession, but overall I think the messages are pretty cute.

And yes, they can get slightly excessive at times.

So much that I now visit certain Facebook/Twitter accounts solely to see the newest romantic back and forth.

Enter the recent news that Ashton Kutcher and Demi Moore are divorcing. In this interesting article, Entertainment Weekly notes that Ashton and Demi were once regarded as the First Couple of Twitter. An excerpt:

The funny thing is that Moore and Kutcher were never particularly funny on Twitter. The attraction, I think, lay in their intimacy. Most celebrities make Twitter a one-way conversation: “I am celebrity. You are fan. We talk now.” The Moore-Kutcher dynamic was more complex — they let you into their intimacy.

Naturally, this makes things a little awkward now. When you decide -- either intentionally or inadvertently -- to make Twitter the third wheel in your relationship, you risk encountering a major dilemma in the event of a breakup.

Who gets custody of Twitter?

Granted, nobody's going to block either one of you from the site. But sculpting a new persona can be challenging, especially when fans have followed you as part of a two-person unit.
