I cleaned up a bit and uploaded my mail aggregator. Getting rid of the pickle was a great move - db seems good enough.
For now I use simple name-value mappings and several db files - it's easier to debug and get other tools to use the same data. I was thinking of a real database - but that would make it more complex and I doubt it'll scale or work better.
I doubt too many people will find it usefull - when they have all the fine 3-panel graphical agreggators. I just use it to read weblogs in train, using my old "pine" and sometimes mozilla/evolution/kmail ( when I feel a need for real nice GUI - and go back to pine when I want to read mail ).
