Mike Jang's proposed readability improvement

[mjang]

In this PR, I'm improving the "readability" of https://qdrant.tech/documentation/overview/. I've used Vale to measure the Flesch-Kincaid readability of that section.

The readability of the current section is > 18. In other words, a typical user would stress as if they were reading a US graduate school textbook.

As shown in the linked screenshot, Vale includes suggestions to address this problem.

The readability of my proposed change is 8.5. A knowledgeable user who can read at a US high school level can understand this content, at a glance.

I don't think that is correct interpretation of the original thought.

Vector databases are not directly useful for Sentiment analysis or Speech recognition.

Truthfully, the whole passage should be replaced with something more meaningful

Thank you @generall . Then I suggest that we close/replace this PR with an issue where we can discuss details.

You stated:

Vector databases are not directly useful for Sentiment analysis or Speech recognition.

The current document states:

"...the data used to train a machine learning model to accomplish a task like sentiment analysis, speech recognition, object detection,..."

The difference is too subtle for all but the most careful reader. If we want to get into such detail, I believe "that" belongs somewhere other than the "Introduction."

(By "that," I'm referring to the list: Sentiment analysis, Speech recognition, and I assume also object detection. Alternatively, we could add links to more detail.)

[mjang]

We could link the example tasks to existing Qdrant use cases (taken from https://qdrant.tech/solutions/)

Suggested change

	- Sentiment analysis
	- Speech recognition
	- Object detection
	- [Similar Image Search](https://food-discovery.qdrant.tech/)
	- [Semantic Text Search](https://demo.qdrant.tech/)
	- [Anamoly Detection](https://qdrant.tech/articles/detecting-coffee-anomalies/)

[mjang]

Alternatively, if these examples are not appropriate, then we could remove them. After all, this is an introduction. Do either of these options make sense, @generall ?

[mjang]

I've tried rewriting this in several ways to avoid the issues that @generall suggests. But they lead to other problems. So I'm closing this in favor of #422 .
