Being a bit of a web geek, I like to keep track of developments in the web2.0 space. There's a lot of new websites popping up everyday now taking advantage of advanced web scripting languages that add interactivity and social networking. Some of them are actually quite exciting and are making a lot of money. Near enough every week I see a new site and think I wish I'd have thought of that!
Mashable is a site that keeps track of these developments and is quickly becoming one of my favourite blogs. They do a lot of research into the features of the various sites and extensively compare them against similar sites in the same category. Some examples of great posts are:
Essential sites for summer travellers: I've used Yahoo Travel Planner a few times now and found it very useful, but by the looks of it there are even better sites out there for planning trips.
90+ online photography tools and resources: an unbelievably extensive guide to the best sites for photo sharing, editing, printing, buying, selling, searching, remixing and free hosting.
