Thanks. Although it might not be what you'd prefer, you can now add two personal tags to a post. The archives idea is one that we are going to have to revisit. It does seem like there is a desire for it. However we have yet to come up with a functionality that isn't overly complex. If you have any ideas how you might like an archiving function to work, definitely share with us. forwardslash was charged this week with investigating solutions to this problem. Hubski has two problems in this regard: 1) we store data in flat files rather than in a proper (relational) database, 2) the Hubski app keeps accessible posts in memory, and does not serve up the whole of a directory in a efficient manner. Personally, I feel that this is one of the most glaring shortcomings of Hubski, and its one that I want to fix. It is holding us back in more ways than one.But currently I can't put one post into two personal tag archives at once.
Ideally: hubski has infinite recall and a google-esque search engine, but practically only the first one is very important.
