blo.gs is a good service based on a good concept, and I have enjoyed using it during the past few months. The goods:
- Updates when the individual site send a ping to blo.gs. This must be the best way to know when a site is updated.
- Autodiscovery of RSS and Atom feeds.
- XFN support
As a test run, I have taken the blo.gs link out and instead use the weblink monitoring which comes with Drupal’s weblink module. What is happening is, basically,
- I added items from my blogroll manually, as if adding just another weblink
- Every one hour, a cron job is run, and my site grab the RSS or Atom feed from these monitored sites, and compare them with old copies.
- If there’re more than 40 kb difference in a feed, the site is marked as updated.
- 20 most recently updated sites are shown on the side bar. (appears only in blog section)
The system is only in place for a few hours, and I’ll have to wait and see if I need to tune any parameters (fetching frequency, change tolerance) to make it more accurate. Also the server load has to be monitored, if I am going to add very quick-update sites like Gizmodo.
If it works well, this site will be totally independent of any outside services. (the new tagboard is also run on ichris.ws)
OK. Time for lunch.
