I expect a few of you were wondering what's been going on with SN lately - no posts to the blog, authentication on the website... Well, the reasons are too arcane and tedious to go into here, suffice to say that we had to sort out a few internal issues, and during that time it seemed prudent to limit access to the service. Now that everything is tickety-boo again, it's time for a progress report. First of all, we plan to provide open access to the site again some time next week (all being well.) We're introducing a registration process, for obvious reasons (persistent login, personalisation etc.) Secondly, we're integrating more third-party data. Thirdly... well, you'll find out soon enough. More info to come...
