Does a chat button make visitors expect an instant reply?

One thing that kept coming up in a recent discussion:

Live chat can make it easier for visitors to ask a quick question but it can also create an expectation that someone is available right now.

For a small B2B team, that can backfire.

A visitor sees a chat widget, sends a message, waits a few hours, and starts to assume nobody is home. In that case, the real-time interface may feel worse than a clear async path.

I'm trying to fix my “staying informed” workflow, but I still spend way too long hunting for news

I've been trying to fix my "staying informed" workflow, and honestly I'm not sure I've cracked it.

I set up AI to send me a daily digest of what's been happening which helps. But I still end up spending a lot of time wandering around different sites, checking whether there's some big news I missed. The digest gives me a baseline, but it doesn't kill the FOMO, so I keep manually poking around anyway.

What are the 5 tools you simply couldn't do your work without?

This could be related to your industry, or even a side project you're working on.

Here are my 5 (I couldn't function without them):

  1. Grammarly proofreading my texts, not just posts, but also client communication

  2. ChatGPT / Claude mostly brainstorming, help with copy, and summarising

  3. Figma I can put the basic graphics together quickly.

  4. Translator sounds incredibly old-school, but English is not my mother tongue

  5. Gmail and not only for communication, but also for storing ideas and sending myself email reminders for posts
