Reviewing an [edit](https://bioinformatics.stackexchange.com/review/suggested-edits/1162) I realized we have some duplicated tags or at least somehow redundant. 

We have [scrnaseq](https://bioinformatics.stackexchange.com/questions/tagged/scrnaseq "show questions tagged 'scrnaseq'"), [rna-seq](https://bioinformatics.stackexchange.com/questions/tagged/rna-seq "show questions tagged 'rna-seq'") and [single-cell](https://bioinformatics.stackexchange.com/questions/tagged/single-cell "show questions tagged 'single-cell'").

Some numbers:

* [scrnaseq](https://bioinformatics.stackexchange.com/questions/tagged/scrnaseq "show questions tagged 'scrnaseq'"): [25](https://bioinformatics.stackexchange.com/questions/tagged/scrnaseq) questions
* [scrnaseq](https://bioinformatics.stackexchange.com/questions/tagged/scrnaseq "show questions tagged 'scrnaseq'") & [rna-seq](https://bioinformatics.stackexchange.com/questions/tagged/rna-seq "show questions tagged 'rna-seq'"): [9](https://bioinformatics.stackexchange.com/questions/tagged/rna-seq+scrnaseq)
* [rna-seq](https://bioinformatics.stackexchange.com/questions/tagged/rna-seq "show questions tagged 'rna-seq'") & [single-cell](https://bioinformatics.stackexchange.com/questions/tagged/single-cell "show questions tagged 'single-cell'"): [7](https://bioinformatics.stackexchange.com/questions/tagged/single-cell+rna-seq)
* [scrnaseq](https://bioinformatics.stackexchange.com/questions/tagged/scrnaseq "show questions tagged 'scrnaseq'") & [rna-seq](https://bioinformatics.stackexchange.com/questions/tagged/rna-seq "show questions tagged 'rna-seq'") & [single-cell](https://bioinformatics.stackexchange.com/questions/tagged/single-cell "show questions tagged 'single-cell'"): [1](https://bioinformatics.stackexchange.com/questions/tagged/single-cell+rna-seq+scrnaseq) (If we approve the linked edit that would be 2)

Should we remove remove [scrnaseq](https://bioinformatics.stackexchange.com/questions/tagged/scrnaseq "show questions tagged 'scrnaseq'") in favor of [rna-seq](https://bioinformatics.stackexchange.com/questions/tagged/rna-seq "show questions tagged 'rna-seq'") and [single-cell](https://bioinformatics.stackexchange.com/questions/tagged/single-cell "show questions tagged 'single-cell'")?  

Or should we retag those 7 questions with both tags in favor of [scrnaseq](https://bioinformatics.stackexchange.com/questions/tagged/scrnaseq "show questions tagged 'scrnaseq'") ?

Related discussion: [Let’s standardise some tags](https://bioinformatics.meta.stackexchange.com/q/5/48)

As stated in the comments of the related discussion I think that the usage of these tags should differentiate between technology and target of the technology. Here [rna-seq](https://bioinformatics.stackexchange.com/questions/tagged/rna-seq "show questions tagged 'rna-seq'") describes a technology and [single-cell](https://bioinformatics.stackexchange.com/questions/tagged/single-cell "show questions tagged 'single-cell'") describes the target of a technology so it would be possible to have other technology targeting the same single cell such as metabolomics or methylation assays, or...
