If you’re into productivity, meaning testing tools and services that might make you a bit more organized, but in the end really just cost a lot of your time, because you can’t decide on the perfect setup, then these news are for you!

We all remember Remember the Milk, the extremely versatile, albeit sometimes too extensive todo-list tool. Apart from integration with Twitter, Google Calendar and a host of other features, they’ve now introduced a plugin for Firefox enigmatically named Remember the Milk for GMail.

The more astute among you will now have guessed what it does, but I’ll spell it out for good measure: the plugin combines the power of Remember the Milk with the, well, extreme power of GMail. Makes two extremely powerful powerplayers powering your life.

I tested it out for your convenience, and well, it’s really quite perfect. By putting the list in the right sidebar, the plugin integrates RTM so smoothly into GMail, you’d think it’s actually a part of the official package. Adding and editing of items can be done inside GMail, as well as a whole lot of other things which I won’t repeat here, because next to a heap of screenshots, the official plugin page actually lists all the features.

Enjoy.

Being one of the first people to have blogged about Twitter, I’m not at all uncomfortable with the role of the Nr.1 specialist on the topic. Sure, there are people like Robert Scoble who send Twitter messages before brushing their teeth, but you know, quantity just doesn’t equate quality.

But on to the point: As it seems, Twitter has introduced a limit on the number of messages one can receive when using their London number (the limit’s 250 messages per week). Which means for everyone in the whole of Europe. They explain this with certain limitations by mobile phone networks, deals they have to strike, in order for us to keep having the pleasure of micro-blogging.

Now, I may be using Twitter, but I seriously don’t need to receive 250 messages a week. Or so I initially thought. The thing is, the more popular Twitter becomes, the more webservices make use of their API. So suddenly the messages you receive aren’t anymore simple recounts of people brushing their teeth (if they’ve already managed to do that before starting their Twitter day), but instead reminders from, say, Remember the Milk or personal assistant Sandy.

What I’m trying to get at here is the following: Now that Twitter has become something more than a mere meme poured into a webservice, people have started to rely on it. And when people start to rely on receiving messages, limiting that number to an amount that could easily be used up by fervent Twitterers just isn’t a splendid idea.

Twitter still holds the top spot when it comes to mobile- and micro-blogging, but there’s always a start-up around the corner that would love to skim off the users who are irritated by measures like this one. Especially when one of those start-ups has recently been bought by The Google.

I’d love to add something like “Heed my warning, Twitter!”, if it wasn’t a tad too melodramatic. But still, do it!
