I've recently been thinking the hype surrounding Twitter couldn't possibly get any bigger, but it seems I was wrong.

Just like pet rocks, Tamogotchi toys and oversized sunglasses, Twitter has come from nowhere to be the coolest thing on the block.

The micro-blogging service that makes no money yet manages to clutter people's lives with worthless drivel has rocketed up the rankings to become one of the most talked-about tech topics on the planet.

Like all crazes, I've been waiting for reason to return and this over-hyped waste of time to slide slowly to the bottom of the "Why did we ever think that was cool?" list. But it seems, unfortunately, this could take longer than I'd hoped.

My online wanderings were stopped this past week by a story about a new PR company set up to help businesses make the most of Twitter. According to the company's website its aim is to build " a suite of apps, tools and services to help brands, media companies, and celebrities harness the power of the Twitter ecosystem".

Pardon me while I choke. They're going to make money from showing companies how to generate business from quirky 140-character text messages? Good luck.

Now, I should say that I do understand the basic concept of Twitter. It's designed to let people gather groups of followers who want to hang on their every electronic word, waiting in hope for their next mini utterance.

But what's the point for business? Does anyone want to recieve Twitter spam from corporates desperate to appear cool and connected? I don't think so.

So let's leave Twitter be. It might be useful for those desperate enough to need a circle of electronic friends or others needing to feel close to those they don't really know. But for the rest of us, it's just an amusing hype cycle.

Here's looking forward to the next one. Let's hope it's got more substance.
