積読記事をSlackに流して自分が読みたい記事を他人から教えてもらうライフハック

![slack.png](https://qiita-image-store.s3.amazonaws.com/0/4194/41b3a0ed-4e74-a27e-e203-0ff6c4ccf162.png)

[Feedly と Github timeline を twitter に流すようにした](http://tototoshi.hatenablog.com/entry/2014/08/13/002120)に触発されてTwitterではなくメンバーが見ているSlackにFeedlyの（自分の）未読記事を流すようにして見ました。

これで自分が読むべきだと思って登録しておいた記事もメンバーの方から「○○の記事おもしろいね」みたい感じに教えてもらって、見逃すことが減るかも！かも！

追記（2014/09/02）

どんな感じで実行しているかイメージ付きづらかったかもしれないので、実行しているcronも追加しました。

```/etc/cron.d/feedly_slack
USERNAME=username
FEEDY_API_KEY=Jfwekfe0h...
SLACK_API_KEY=04fff-afnjafasfkj...
SLACK_CHANNEL=#news

00 8-22 * * * root su - $USERNAME -lc "cd /home/$USERNAME/feedy-slack && FEEDY_API_KEY=$FEEDY_API_KEY SLACK_API_KEY=$SLACK_API_KEY SLACK_CHANNEL=$SLACK_CHANNEL bundle exec ruby bot.rb" >> /home/$USERNAME/feedy-slack/tmp/cron.log 2>&1
```
