I find it interesting how advances in web technology come in waves. Weblogs have been around forever, but blogs really came into their own with the development of simple CMS apps that ordinary folks could use (instead of manually editing and uploading every time they had something new to say). And each new advance begets a new problem.
With blogs that incorporate comment systems has arisen a new need: the need to keep track of the comments one has written. I like to follow up on comments that I leave on other people's blogs, so after commenting, I drag the link to a folder in my bookmarks toolbar in firefox. Then I occasionally revisit the links in the folder, deleting where necessary. It's not efficient, and I'd like to see some automation. Some scattered sites and systems have their own systems that work by email, such as LiveJournal and Movable Type. But that's not enough. There needs to be a system independent of the CMS in use by a site. I know others must be feeling just as frustrated.
What do you do manually on the web that can be automated? What will the next advance be?
