Occasionally I have insomnia and the only way I can get back to sleep is get up and accomplish something. Anything. So, last night, I wandered downstairs at 2:45 a.m. and flipped on the computer. I skimmed the first few entries on Google + and stumbled onto Louis Gray’s post about another new service, Subjot. I took the bait, and visited the site.

It immediately captured my interest, mainly because it fills a hole that Twitter has left gaping wide open – the ability to view a stream based on the content you are interested in, rather than the person you are interested in. Yes, it looks a whole lot like Twitter, with its “bites” of information in short form (250 characters to be exact) flowing by in a stream, or more precisely at this early stage, a trickle. But there are a few meaningful differences. Subjot leads with its subject matter tags, rather than its users. You can, of course, follow people, but to do so, you have to select one of their subject areas. These are determined when people post their bites – you have to assign a category or tag describing the subject matter of the post. A post about Subjot should be tagged, obviously, with the Subjot tag. If you follow someone and have indicated you want to follow them for their expertise on Subjot, then this post will appear in your stream. However, when that same person posts about, say, Wagnerian Opera, which you have chosen (for better or worse) not to follow, you will NOT see their post about Ride of the Valkyrie in your stream.

Another very cool feature that is baked in, but which requires a bit of finagling to achieve on Twitter, is the ability to readily comment about and see the conversation surrounding a particular post. Like you might find on Google +, there is the initial post and then related comments appended or nested with that post within the stream. You can find people by topics and browse topics themselves to build your stream in precisely the form you want. And, if your follows properly tag their posts, you will see your interests, your whole interests and nothing but your interests in your stream. Pretty freaking cool.

Right now, Subjot suffers, if anything, from a lack of user base. It is in invite only beta right now, but I happen to have a handy invite link if you are interested in checking this smart new service out. Just click here. Hope you like it as much as I did – I felt so accomplished I was able to fall right back asleep in no time!
