Is there any app that sorts your followers by time/date of last tweet? Would be a good way to weed out those that don’t participate

There seem to be quite a lot of people looking for a way to manage their followers / friends on Twitter. These two requests show one way of doing it – by culling those that aren’t participating.

Is there an app that easily allows you to unfollow inactive tweeps?

Is there a service that takes business cards, scan the text, and can send me a CSV file?

This could be a good add-on service for someone like printers – they have easy access to scanners, and could be a good way to build up a relationship with customers between their print runs. The CSV file is a great idea for allowing you to import them into an email address book, but even scanning the stack of them I have would be a good start.

s there such a service that measures the level of crowds you’re most likely to encounter during your vacation in a particular location?

I quite like this. I’m not sure where the data would come from, but I’m sure there’d be some available from different sources.

Is there a Gmaps mash-up/app for public transportation that regards your distance to the station & the possibility of getting there in time?

Again, a really good idea – both the location data & the service information for this one would be a bit more readily available.

Are there any good apps out there that act like an offline personal wiki for the iPhone or ipodtouch?

I launched TwitEye.com a couple of months ago as a way of showing the range of ideas that are publicly available. I got some good feedback, but I saw that the traffic came in spikes; anytime it was mentioned (usually on Twitter), I’d see another bump. Because people had no way of keeping up with what was happening on the site (apart from visiting it and watching the stream), I decided to add an RSS feed for daily ideas.

The idea is that some of the more interesting ideas in the homepage stream will be published through the RSS feed. Rather than dumping the whole stream into the blog feed, there’ll be one added each day. The posts are scheduled to start appearing tomorrow.

If you haven’t seen it before, you can read the original blog post that introduced TwitEye.
