After watching Rui mention Newspipe so often, I finally got around to try it out. For my needs, it’s not really a replacement for a “normal” aggregator such as Bloglines, but it offers me something else…
Newspipe is a small utility, written in Python, which converts a feed to HTML and sends it by email - by default, one email per post, but it can also do digests (all the new posts in a single email), and it’s customizable in several ways (for instance, to remove images, send text only, etc.).
Now, unlike Rui (I think), having news feeds in Thunderbird or Gmail isn’t really useful to me - I’d much rather read the stuff in Bloglines.
On the other hand, there are some feeds I usually only skim through, which are interesting but not prioritary. So, I had an idea - why not send those to an email account, which I can access by IMAP, with my cell phone? Whenever I have to wait for something, or I’m bored, and away from a computer, I simply take my N-Gage or my 6630 out of my pocket, open Profimail, and see what’s new from a small group of feeds - the ones I used to skip often in Bloglines.
After less than a day, it’s already been useful.

Grab the CVS version and check out the “contrib” directory. You’ll find a mobile web front-end there.
Thanks, but, to me, reading the posts in Profimail (and downloading them all, then reading them offline a bit later) is perfect.
