FIXME

1) Check feed duplication on runtime.
    When feed is valid and is not yet in the database it is
    posible to send a batch which would result in duplication.
    Consequently, it might result in database lock error upon
    feed removal attempt

TODO

1) SQL prepared statements;

2) Machine Learning for scrapping Title, Link, Summary and Timstamp;
   Scrape element </article> (example: Liferea)
   http://intertwingly.net/blog/
   https://www.brandenburg.de/

3) Set MUC subject
   Feeds which entries are to be set as groupchat subject.
   Perhaps not, as it would require to check every feed for this setting.
   Maybe a separate bot;

4) Support categories;

5) XMPP commands;

6) Bot as service;

7) OMEMO;

8) Logging;
   https://docs.python.org/3/howto/logging.html

9) Readability
    See project /buriy/python-readability

9.1) IDEA: Bot to display Title and Excerpt
     (including sending a PDF version of it) of posted link

10) Fetch summary from URL, instead of storing summary, or
    Store 5 upcoming summaries.
    This would help making the database files smaller.

11) Support protocol Gopher
    See project /michael-lazar/pygopherd
    See project /gopherball/gb

12) Support ActivityPub @person@domain (see Tip Of The Day).

13) Tip Of The Day.
    Did you know that you can follow you favorite Mastodon feeds by just
    sending the URL address?
    Supported fediverse websites are:
        Akkoma, Firefish (Calckey), Friendica, HubZilla,
        Mastodon, Misskey, Pixelfed, Pleroma, Socialhome, Soapbox.

14) Brand: News Broker, Newsman, Newsdealer, Laura Harbinger
    
15) See project /offpunk/offblocklist.py

16) Search messages of government regulated publishers, and promote other sources.
    Dear reader, we couldn't get news from XYZ as they don't provide RSS feeds.
    However, you might want to get news from (1) (2) and (3) instead!

17) Make the program portable (directly use the directory assets) -- Thorsten

18) The operator account will be given reports from the bot about its
    activities every X minutes.
    When a suspicious activity is detected, it will be reported immediately.

19) Communicate to messages of new contacts (not subscribed and not in roster)
